TIRA permanent-magnet shakers are used as portable and stationary systems for the simulation of environmental influences. Typical applications are structural analysis and testing of smaller assemblies. The robust construction of the shakers guarantees a long service life. TIRA shakers are characterized by high lateral stiffness. TIRA has met the requirements of the industry for lightweight construction of the shakers. New rare earth magnets have been added to the usual Alnico magnets. This has resulted in a reduction in mass from 36 kg to 12 kg, which guarantees easy handling of the shakers especially in mobile use. These shakers have proven their worth in applications such as environmental laboratories and universities as well as in industrial production lines for component testing and calibration. These complete system offers allow users to test according to national and international standards such as DIN, ISO, BS, MIL, IEC and ASTM.

Water-cooled TIRA shakers are guided hydrostatically and cooled by a closed water circuit. The external cooling unit also supplies the lubricant for the hydrostatic bearings, which enables frictionless positioning of the vibration armature. Water-cooled shakers have the advantage of generating high forces for testing heavy loads with high accelerations. Specimen masses up to 910 kg are possible. A fully automatic pneumatic load compensation system enables the nominal vibration displacement to be reached even at high specimen masses.

Measurements for determining vibration transmission and vibration analysis are increasingly being carried out in all areas of industry, aviation, the automotive industry and power plants.
In order to be able to carry out such tests, a large number of measuring sensors are necessary. The sensors must be checked and calibrated for accuracy at defined time intervals. Since most transducers have a high measuring range and wide frequency ranges, special shakers are required to calibrate the transducers.
TIRA has taken up this challenge and developed a shaker that meets these requirements. This newly developed shaker consists of a ceramic vibration system and a special guide system. This newly developed vibration system is characterized by its very high, usable frequency range up to 25 kHz and is ideally suited for professional calibration with the appropriate measuring equipment. Note: The calibration shakers are not designed for continuous operation at maximum power.
The "AC" calibration shaker additionally has a special air bearing which offers the advantage of friction and wear-free operation and also dampens interference vibrations.

TIRA provides a series of modal exciters from 100 N to 2.7 kN specifically for the requirements of modal and structural analysis.
Up to 400 N, the modal exciters are excited by permanent magnets, whereby the exciters, which are manufactured especially with rare-earth magnets, convince by their lightweight construction in mobile use. The construction of the modal exciters is characterized by high lateral stiffness. Modal exciters from 1000 N upwards provide a vibration displacement of up to 50.8 mm. This is made possible by a TMC control. The electronic zero point control TMC enables an exact coupling of the modal exciter to the test object. The axial stiffness is also electronically adjustable.
All modal exciters are equipped with a trunnion as standard. A variety of coupling options are offered.
The modal exciter systems TV 51120-MNC and TV 51130-MSC are a special development of TIRA to increase mobility. The 200 N shaker does not require any additional cooling unit and the 350 N shaker has an integrated air cooling system, which eliminates the need for an additional external cooling unit.

TIRA offers a new range of special modal exciters for mobile use. The MOSP models feature a large vibration displacement of up to 25.4 mm. The low mass by using rare-earth magnets, the through hole in the center of the armature for using piano-wire stingers in addition to the traditional push/pull stingers, are further positive features of this model series.
TIRA offers a series of modal exciters from 4 kN to 15 kN especially for modal excitation of large structures or structures with high mass. The construction of these modal exciters is characterized by high lateral stiffness. Modal exciters from 4 kN upwards provide a vibration displacement of up to 100 mm (pk-pk), which is achieved by means of a TMC control.
The electronic zero point control TMC enables an exact coupling of the modal exciter to the test object. The axial stiffness can be easily adjusted.

TIRA manufactures a range of inertial exciters (IN) from 125 N to 650 N. The inertial exciters (IN) are screwed directly to the structure and can be coupled at any angle in 360 degrees to the structure.
These inertial exciters (IN) are characterized by high lateral stiffness. The permanent magnet driven inertial exciters are equipped with a special spring system which provides an optimal guidance. This allows the exciter to work on the structure with its full body mass with no problems.
A maintenance-free fan guarantees the cooling of the vibration exciter. The cooling air is suctioned through a coarse filter system. TIRA's inertial exciters (IN) are used in industry, aerospace, civil engineering and the shipbuilding industry, as they are a favourable and effective method for transferring dynamic forces into large structures.

As a result of growing safety requirements, the industry is increasingly developing sensors and components that have to be tested under extreme stress conditions. The test parameters reach higher and higher accelerations combined with long shock duration - these tests are no longer possible with conventional standard systems with a vibration displacement of 50.8 mm.
TIRA has responded to the requirements of the industry for testing systems that can simulate extreme shocks by developing a series of long stroke exciters with 100 mm vibration displacement (pk-pk). In addition to their use in the laboratory for testing development tasks, these shakers have also proved their worth in the integration into complete
production lines.

The clear and functional design of TIRA slip tables enables user-friendly handling and trouble-free testing. Swiveling the shaker does not limit the possibility of conventional vibration tests on the vibration armature. Rigid welded structures as a basis increase the reaction mass of our systems. Undesirable vibrations on the surrounding area are damped. Linear guides guarantee the lateral stiffness of the slip plate and minimize lateral vibrations in asymmetrical test arrangements.

Tailor-made manufacturing is our success. We offer customer-specific solutions which can be adapted to all special requirements. TIRA slip tables can be optionally adapted to all existing vibration and climate test systems. By the use of high-quality materials and reliable components, our products ensure long-term use at low operating costs.
Modern systems and installations have to prove themselves in all areas under their operating conditions such as temperature changes, vibrations and high humidity. From the conceptual design stage to the final inspection of electrical, electronic or mechanical products, combined vibration-climate testing systems simulate environmental influences on the test object. Weak points can be detected early and optimized cost-effectively. Expensive downtimes and damage are avoided by the correct design of functionally relevant components. These multi-test systems are important elements of quality assurance in the production process.
TIRA driver bars provide the link between shaker and slip plate. They are FEM designed and made of magnesium. Depending on size, they are single pieces or welded together. Their geometric design enables perfect force transmission while minimizing the moving mass. Driver bars are available for vibration generators with different armature diameters from 120 mm to 840 mm.
Air spring elements allow the use of the slip tables without expensive foundations. Due to the low natural frequency of the isolators (3 - 5 Hz) a wide test spectrum can be applied.
Test objects must be excited in their final position for practice-oriented simulation. TIRA supplies individual clamping devices for each application.
Increasing requirements in vibration testing demand additional slip table systems, which also allow testing of large and heavy specimens in horizontal mounting positions. The monobase design ensures fast and precise alignment and coupling of the shaker to the slip table. The slip tables are available as standard with slip table plates up to 2000 mm x 2000 mm. Different and larger tables are manufactured according to customer requirements. The oil film slip tables consist of a precision ground and lapped natural granite base plate on which a magnesium plate slides onto an oil film. 4 Linear guides ensure the lateral guidance of the slip plate and minimize lateral vibrations. The possibility of horizontal and vertical excitation allows tests in mounting position. Vibration isolators are mounted on the bottom of the frame as a standard feature to prevent vibration effects on the building.

Oil-film slip tables with hydrostatic guidance from TIRA give you a compact system for a variety of vibration tests, including those of large and heavy specimens which generate high yaw, roll and pitch moments due to their high centers of gravity above the slip plate. These tables use high-pressure bearings with a separate hydraulic supply unit.
The monobase design enables rapid conversion from horizontal to vertical testing and the accurate alignment of vibration generators relative to slip tables. Magnesium slip plates are available in different sizes, up to a working area of max. 2000 x 2000 mm. Other (and larger) sizes can be produced on request. Oil-film slip tables consist of a precision ground and lapped natural granite block with a magnesium plate sliding on an oil film.
Hydrostatic slide bearings make it possible to restrain the high yaw, roll and pitch moments as they appear with heavy test items or very large loads which may have a high centre of gravity. Hydrostatically guided slip tables are used to test specimens in a horizontal direction. Vibration isolators are provided on the underside of the frame as a standard feature to prevent vibration transfer to the building.

TIRA offers a wide range of head expanders, L and T-type fixtures, cubes and special support systems. The latest software for FEM calculation and analysis is used so that customers get specifically designed fixture assemblies with optimized and predicted dynamic performance to produce the best result.
Fixtures are often main items of application conditions in industrial testing where specimens are tested to high standards of precision. This means that the fixture has to be optimized for both the specimen and the test parameters. Many customers, however, can't do these sophisticated calculations to produce a suitable fixture. TIRA has met this challenge and will develop, calculate and manufacture any type of special-purpose fixtures for your application, with the emphasis on minimizing its mass and optimize its dynamic performance.
Monobase systems with a horizontal slip table and vertically guided load-bearing platform make it possible to test extremely large and heavy loads in direction of x, y and z axis. Specially-designed slip tables and load-bearing platforms are available with a working area of max. 2000 mm x 2000 mm (78 x 78"). Slip plate and load-bearing platform are accurately aligned in a common base frame. Conversion from horizontal to vertical operation is easy and takes a minimum of time.
TIRA head expanders are manufactured from magnesium and provide an expansion of the armature table. The unique design of the head expanders and 3 channel control strategies allow tests up to a frequency of 2000 Hz (depends on resonance frequency). Head expanders especially provided with 'vibrodamp' can be subjected to test frequencies above 1000 Hz. This damping process reduces amplification of upper frequency resonances.
If a test object needs eccentric clamping or generates high transverse moments, Tira also offers guided head expanders.
Apart from the range of standard head expanders TIRA also offers customized fixtures for round, square or rectangular working areas.

TIRA has developed a new leadthrough for the operation of shakers with climatic chambers. This leadthrough allows in comparison to the previous systems with headextender and massive thermobarrier plate a significant better isolation at high temperature differences.
This way an operation of sensitive climate with higher dew points is better possible.
Therefore more constant temperature conditions for the test material are present. The condensation of humidity out of the testing air is reduced considerably. At cooling operation of the chamber the shaker inside is better protected against condensation.
The new model offers in addition to the significantly enhanced isolation attributes also a mass advantage of about 30%.

The cooling units include the complete primary circuit of shaker cooling system for the TIRA water-cooled shakers and the hydraulics of the shaker’s hydrostatic bearings.
The units are designed as compact mobile devices. Primary circuit is based on deionised water. The extraction of the heat is carried out by a customer-provided secondary-process water circuit. Pressure gauges and flow indicators are available at many positions.
The devices include their own control circuit based on PLC. The front and side walls are designed with swing doors to ensure a good accessibility to all built-in components. The connections to the shaker are accomplished by hoses with self-sealing couplings that are free from leakage.
The water cooling units have the following benefits compared to other known systems:
-
The primary circuit is designed as closed system, which guarantees no evaporation loss of the water and no pollution of the circuit.
-
The closed system operates at a higher pressure level. This way the usual interferences of the measuring signal by cavitation are eliminated.
-
The flow rate of the splitted lines of the primary circuit to moving coil, field coil and short-circuit rings is monitored.
-
The primary circuit features besides the conductance monitoring an integrated demineralization cartridge, which keeps the conductance low within the bypass flow for a long operation period.
-
The primary circuit offers a fine filter with pollution monitoring.
-
The units control the process water flow. This way the water consumption can be reduced at low process water temperatures and during part load operation.
If needed, an additional fine filter unit for heavier polluted process water is optionally available.
TIRA offers a new series of amplifiers with a rated sinusoidal power output up to 1200 VA. The modules control all permanent magnetic shakers as well as shakers in connection with an internal field excitation up to 1000 N.
These amplifiers, equipped with highly-advanced MOSFET transistors, can be run in the current or the voltage mode, as desired. The amplifiers are user-friendly because of their backgroundlit multifunctional display.
A safety management system monitors functions such as temperature, overcurrent and overtravel.
A high signal-to-noise ratio and a low distortion factor are outstanding features. Selectable ranges of operating voltage and current range limiting are preconditions for the fact that TIRA amplifiers can be readily adapted to other shakers from other manufacturers.
Optionally, the amplifiers are designed for connecting the electronic zero-adjustment unit “Tira Middle Control“ (TMC), which makes even with small longstroke-shakers a load compensation for achieving the nominal displacement possible. A remote control in hardware or software is availble on request (BAA 500 and BAA 1000).
Analog power amplifier BAA 1000-ET with Field Power Supply (FPS) and electronic zero adjustment (TMC)
The Gradient Amplifier from TIRA is a single axis pulse width modulated amplifier. The Amplifier's exceptionally low output noise, extremely high bandwidth and excellent stability make it ideally suited for demanding power amplifier tasks found in laboratory and medical applications. Utilizing advanced hybrid digital and analog control architecture,
the TIRA Power Amplifiers provide a host of powerful features.
On the LCD-touch screen display the module status with current indication and the error diagnostics are shown. A safety monitoring unit protects the amplifier from short circuit and from a possible destruction of the modules. Error indication and system parameters in plain text increase the availability thanks to a faster diagnostics. The high clock frequency of up to 102 kHz allows test frequencies of up to 4000 Hz without any decrease in output power. The cascading of the modules allows an amplifier design up to 240 kVA at low floor space requirements. The output voltage of the modules can be modified so that TIRA amplifiers can be adapted to almost all shakers existing on the market.

The hardware platforms support the extensive functionality of the software, which includes simple sine or random tests over complex tests with random signal excitation, that is overlayed with a multiple sine signal, up to a load simulation in time intervals. Of course all tests are accomplished according to the respective standards ISO, DIN, MIL, ASTM and IEC.
Part of a complete vibration test system is besides the shaker and control system also a vibration accelerometer. These accelerometers are mostly of piezo-ceramic type. They are used as standard accelerometers for electrodynamic shakers due to their excellent linearity at wide dynamic range and large frequency range. TIRA offers a wide variety for all types of application.
Due to the requirements of the automotive industry for a 3-axis simultaneous testingmachine, which can cover a wide frequency range up to 2000 Hz, Kokusai developed a 3-axis testing machine with the aim of meeting the specifications according to MIL standard suitable for the automotive and aviation industries.
As a manufacturer of vibration testing systems, TIRA GmbH produces and supplies the necessary components such as shakers, amplifiers and cooling units in a joint project and also implements the necessary control hardware and software.
