摘要
Abstract
The vibration analysis of vibration isolation system for crystal oscillator is done in ADAMS. First, the dynamics model of the vibration isolation system is set up. Some unnecessary fasteners and holes in this model are deleted. And the most complex component, the wire rope isolator in the model is simulated by the use of force units. The three-dimensional entities whose relative positions are fixed are restrained by the fixed joints. Then, the input and output channels are established. The acceleration power spectral density is taken as the input, and the acceleration response of the center on the surface of the crystals is as the output. Finally, the transfer function curve, the acceleration power spectral density curve and the mean square value etc. are gotten. From these graphics and numerical value, the effect of the system' s resonance frequency, and the specific frequency on the anti vibration and the overall anti-vibration are judged.关键词
