Electrodynamic Vibration Testing Systems LABTONE - EV240-EV470

Labtone EV series of vibration test machine simulate the vibration environment under the laboratory condition and test the impact strength as well as reliability of various vibration test applications. In the laboratory, with the aid of a vibration testing system, simulations of reproduction of sinusoidal, random, resonant search and dwell, classical shock and road models, etc. can be achieved. It is essential for product quality assurance, new product research and development.

A complete set of vibration testing system is composed of a shaker, power amplifier and vibration measuring control system, in accordance with the relevant national and international standards (such as MIL-STD, DIN, ISO, ASTM, IEC, ISTA, GB, GJB, JIS, BS, etc.) to provide technical support for establishing product quality inspection.

Applications of Vibration Test Machine

  • Automotive parts and systems – qualification testing
  • Electronic assembly, computer equipment testing
  • Avionics and military hardware testing
  • Satellite component testing
  • Product and package testing
  • General stress screening

Selection of Shaker Model

To choose a suitable vibration test system, the most important thing is to know the exciting force required to perform the vibration test. To evaluate and calculate the exciting force, the following data should be specified:

  • Frequency (frequency range)
  • Maximum Acceleration
  • Maximum Displacement
  • Maximum Velocity
  • Specimen Mass and Fixation

The specimen fixation is selected based on the upper limit of test frequency and specimen size, either vertical expansion platform or horizontal slip table. Specimen mass is needed to evaluate the required exciting force for vibration test.
