摘要
以柔性基础上隔振系统为原型，建立了一种综合考虑无源与有源控制模式两方面因素的，复杂弹性耦合系统的一般理论模型，研究了其传递功率流的计算方法，并通过对其功率流传递谱的数值仿真计算，分析了有源作动元件对系统动态特性的影响，并对相关的柔性基础结构噪声的控制策略进行了探讨．
A general theoretical model of coupled flexible system is established, in which both the passive and active control mode are considered. The power flow transmission in such systems is studied, and the influence of active executor on the system dynamic characteristic is analyzed. And further, based on the analysis the structure-borne noise control strategy is proposed.
