Abstract

This paper analyzes the dynamic relation of asymmetric multi-supported vibration isolation system with elastic foundation, establishes the passive and active control model for the system by using the effective matrix analysis method, analyzes and calculates the transmission mechanism and characteristic of vibrational power flow in the flexible vibration isolation system under passive control. In order to meet the need of the practical engineering, the paper analyzes and calculates the effect of the machine mass on the input and the transmission power flow in detail. At last, the paper studies the optimum control of transmission power flow by using the active control technology.
