Active control of flexible vibration systems with inclined combined mounts

In order to reduce the vibration and noise of flexible systems subjected to multi-excitations efficiently, thepaper presents a general model of isolation systems with inclined mounts using the subsystem mobility technique and transfer matrix approach. In the model, the passive-active combined mounts are comprised of passive cylindrical rubber isolators and active axial actuators. The passive isolators are fixed to the seats to react against axial force, transverse force and couples, and the inside actuators which are parallel with the passive isolators and pined-pined at the seats produce axial active forces only. The power flow transmitted into the foundation is considered as a cost function for optimal control and investigating the transfer characteristics of vibration. Some numerical examples are presented to show the effectiveness and the feasibility of the model, and also some useful conclusions are obtained. © KRISHTEL eMAGING SOLUTIONS PRIVATE LIMITED.
