Paper Abstract

Vibration environment is one of most important environmental factor that may cause product failure. The simulation of vibration environment in laboratory is very necessary. This paper describes a vibration controller that can simulate vibration on electro-dynamic and hydraulic shakers. The vibration is generated according to the test profile by electromagnetic or hydraulic shaker. The test profile is defined in shock waveform, random PSD, sine, or sine on random. The controller is a computer-aided-test system. By compensating the dynamic behavior of the shaker system, fixture and test items, it can replica vibration environment to meet the demand of test profile. The control strategy and software implementation of the controller are presented in this paper.
