Vibration testing

The purpose of vibration tests is to determine the ability of components, equipments or other products to operate without degradation, to resist mechanically and structurally when subjected to vibrations of a harmonic (motor), random or both simultaneously. These tests are commonly associated with temperature and damp heat tests. The most common tests are the tests of sinusoidal vibrations, random vibrations, sinus vibrations on noise, vibrations noise on noise ect.
