| 摘 要： | 本文从经典的二个对称面隔振理论入手,讨论了次级系统之间的耦合性,而后应用小参数法系统地推证了次级系统之间弱耦合对固有频率的影响,最后通过实例给出固有频率变化的参考值。

| Abstract: | From viewpoint of the classical isolation theory of two symmetrical planes the auther discusses the coupling characteristics between subsystems.Then,by applying the perturbation method,the influence of weakcoupling on the natural frequency is analyzed. A practical engineering example is given showing the reference values of change of nafural frequencies. |
