| 摘 要： | 综合考虑工程实际中多激励，多支承机组的柔性安装问题，建立了主被动复杂柔性隔振系统的统一动力学模型，将导纳方法推广到主动隔振分析中，采用了子结构导纳综合法对弹性板基础上主动隔振系统的传递功率流进行了分析，并从插入损失的观点探讨了功率流的主动控制策略，揭示了含有主动作动元件的柔性耦合系统的功率流传递机理。

| Abstract: | Considering of flexible installing of machines,which were supported by multi mounts and disturbed by multi excitations in engineering practice,a general dynamic model for the complex active passive flexible isolation systems is presented.The mobility approach is extended to the analysis of the active isolation systems,and the power flow transmitted into the plate like foundation of the systems is studied using substructure mobility synthetic technique.Then the active control strategies of the power flow are discussed from the viewpoint of insertion loss,and the transmission mechanism is revealed for the flexible coupling isolation systems which comprise active elements. |
