Based on mobility matrices of subsystem, the dynamics characteristic of the flexible multidimensional isolation system is investigated; the control effects of different strategies are studied by using the power flow as the appraised target. The studies show that the active control strategies worked in the frequencies domain after the rigid body modes in the multidimensional flexible system, in all strategies put forward in this paper, the total power flow minimum is much more effective, it can decrease the amount and the value of the resonance; the axial power flow minimum nearly have no control effect.

采用子结构矩阵分析法,分析了多维柔性隔振系统的动力学特性;以传递到柔性基础的功率流为评价指标,研究了不同的主动控制策略下的控制效果,研究表明:多维柔性系统中越过刚体振动模态的频域,是主动控制起作用的频域,在提出的控制策略中,总功率流最小化控制效果最为理想,能使共振峰值的数量和数值都得到有效衰减;垂向功率流最小化控制几乎无控制效果。
