Abstract
Electronic equipment system is always manufactured as a super precision system. However, it will be used in harsh environment. For example, the computer in moving carriers will acted by vibrations. The objective of this paper is to provide a systematic investigation to computer-aided design of the vibration isolator for protection of electronic equipment in harsh vibration environment. This papers deal with fast solving method of natural frequency and system response of six DOF (Degree of Freedom) vibration isolator system. In the foundation of a mathematical model of vibration motion differential equation, the state space method is derived and presented. Through transforming the vibration isolation differential equations into the state space equations, it is convenient to facilitate the solution of vibration isolation coefficient of vibration isolation system of six DOF of freedom, by using the state space method and the MATLAB/Simulink model. Comparisons with reality data, Simulation results showed the result is consistent with the reality result. The state space method can find further applications on the selection of vibration isolation system and the evaluation of vibration isolation efficiency.
