针对设备上楼时的弹性安装问题 ,把弹性基础建模为柔性梁 .考虑了设备、隔振元件和基础的动力耦合作用 ,采用传递导纳矩阵法推求主动隔振和被动隔振的统一的力传递率控制式 ,并用 PID方法设计控制器的控制律 ,探讨了各反馈增益对振动控制的影响 ,从而实现了控制 FBRE系统若干阶模态振动的目的 ,隔振效果明显 Considering the dynamic coupling between equipment, vibration isolation elements and foundations, the admittance matrix method is used to deduce the unification of active vibration isolation and passive vibration isolation Force transfer rate control formula, and the PID control method of the controller design to explore the impact of the feedback gain on the vibration control, so as to achieve the purpose of controlling some mode vibration FBRE system vibration isolation effect is obvious
