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。
This paper starts from the classical two symmetric vibration isolation theories and discusses the coupling between the secondary systems. Then the small-parameter method is used to systematically deduce the influence of the weak coupling between the secondary systems on the natural frequency. Finally, Give the reference value of natural frequency change.
