Vibration and shock test (vibration tests)
The Republican Production Unitary Enterprise “Precise Electromechanics Plant” offers its services for testing the effects of vibration and shock (vibration tests).
The tests are carried out on the equipment of a modern vibration testing system by specially trained, highly qualified personnel.
Vibration test system equipment allows to reproduce environmental conditions in strength studies and reliability in all areas of vibration and shock testing, simulate experiments in sinusoidal, broadband random, mixed modes using systems indispensable for quality control, research and development.
The design of the vibration test system allows testing in horizontal and vertical directions.
