Characteristics of power flow and optimal control strategy in the flexible vibration isolation system

针对实际工程中力和力矩复杂激励下柔性耦合系统的隔振问题 ,综合考虑弹簧的纵向和横向刚度 ,运用导纳矩阵法推导了主动控制力下系统的动态传递方程。分析了力的对称性及弹簧刚度对传递到基础的功率流的影响 。

Considering vibration isolation of the flexible coupling system by complex forces and moment excitation in practical engineering,both the longitudinal stiffness and transverse stiffness of the spring are taken into account.The dynamic transfer equations of the system are deduced with the use of the method of mobility matrix.The effects of the symmetry of the forces and the stiffiness of the spring on the power flow transmitted to foundation are analyzed.The effect of the optimal strategy is discussed.
