提出了一种适用于复杂结构系统受稳态随机激励作用情况下的振动隔离系统的优化设计的新方法，该方法同时对振动隔离器的安装位置及隔离器的结构参数进行优化计算，使得整个隔振系统的效果达到较高的水平，同时计算工作量大大减少。由于未加系统模态耦合的限制条件，该方法对复杂系统能方便地进行分析计算。

Optimization of the Parameters of Nonlinear Random Vibration Isolation Systam

An optimal design method of vibration isolation system suitable for complex structures under stationary random excitation is proposed. This new method determines the installation position of vibration isolators and optimum control force on the determined positions,and searches for the optimal parameters of the vibration isolators on the basis of optimized control forces. Therefore, the forces translated by the isolators to the main systems can be made very much closer to the optimized control force and vibration level is lower than the permitted level. The repeated analyses of the system dynamic characteristics can be omitted a lot and the calculation speed can be quicken very much, the optimal installation positions and parameters can be obtained simultaneously. Because the prerequisite that the modes do not affect each other is not used, it can certainly be applied to the complex structures conveniently.
