VIBRATION TESTING LABORATORY
TIRA products are subject to strict quality assurance procedures designed to meet CE requirements as well as national and international norms. Quality management has been certified in terms of DIN ISO 9001 since 1995, and DIN EN ISO 9001:2000 since June 2003.
TIRA vibration generators reproduce ambient conditions for studies of endurance and reliability in all fields of vibration testing. Designed for long-time operation , they are characterized by high cross axial stiffness . The electrodynamic generator is supported in a rugged revolving frame for excitation in vertical or horizontal direction.
Nominal displacement is automatically achieved by pneumatic load compensation even for heavy test loads. As a standard feature, the frame is provided with vibration isolators which minimize vibration transfer to the floor so that in most cases no extra foundation is needed. The generator is cooled by a maintenancefree fan, with cooling air entering through a filter assembly. TIRA vibration generators, amplifiers and vibration control systems form complete test systems to document product quality in conformity with international standards (such as DIN, ISO, BS, MIL, IEC, ASTM).
TIRA offers a new series of analogue amplifiers with a rated sinusoidial power output up to 2,000 VA . The modules control all permanent magnetic shakers as well as shakers in connection with an internal field excitation up to 1,600 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 background-lit multifunctional display. A safety management system monitors such functions like temperature, overcurrent and overtravel and avoids the destruction of the amplifier in case of short circuit.
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 manufactures. According to standard, the amplifiers are designed for connecting the electronic zero-adjustment control unit TMC. Thus, even with small shakers a load compensation for achieving the nominal vibration.
