摘　　要：用功率流指标描述主动隔振系统中能量的传输 ,以传输到接受体的功率流最小为最优化控制目标 ,推导主动隔振系统中功率流传递的最优控制表达式 ,提出了一种基于SMR主动隔振模型的主动功率流的最优化控制策略 ,对比分析了被动和主动模型下总功率流的传递特性以及主动控制时传递到基础的各功率流分量的分布特性。针对工程实际中的柔性安装问题 。In this paper, the optimal function of the transmitted power flow is deduced in the active isolation system, where the transmitted energy is described by the index of power flow and minimum of the power flow acts as optimal value, and then a strategy of controlling power flow is presented based on the SMR model. The transmission characteristics of total power flow in the passive and active systems are analyzed contrastively, and the distribution behavior of the power components in the active system is discussed. Finally, aimed at flexible installation of practice engineering, the active isolation of a rectangular plate supported simply at the four edges is studied.
