Vibration Testing equipment

These test are needed for, vibration testing

  • Product qualification
  • Quality assurance
  • Accelerated life test
  • Transport test
  • Prototype evaluation

An electrodynamic shaker is used for vibration and shock testing of small components to large payloads up to 600kg.

Sinusoidal Vibration

Sinusoidal vibration tests are used to detect any mechanical weakness of the specimen, to verify its robustness and to assess its dynamic behavior. They also provide a safe method to identify resonance frequencies in the product.

This type of vibration tests, reproduced as a sweep or by excitation at fixed frequency, gives an indication of the fatigue strength of the product under test.

Random Vibration

Random vibration tests are used to simulate real vibration conditions such as transport, mechanical operation or manipulation i.e., airplanes, space and land vehicles. This type of vibration simultaneously excites all product resonances and determines whether it supports real-world vibrations.

It is not a test with isolated frequencies but, rather, these are applied in a random way with a spectrum that constantly changes in amplitude and phase.

Mechanical Shock Tests

A shock (impulse) is a mechanical alteration characterized by a rise and drop of acceleration within a short period of time. It corresponds to a sudden and frequently, severe transient phenomenon.

It is defined by specific amplitude of acceleration, interval and a certain pulse shape (half sine, terminal peak sawtooth, trapezoidal, etc.).

Other types of vibration and shock tests

  • Sine On Random
  • Random On Random
  • Sine Random On Random
  • Shock Response Spectrum (SRS)
