Research on Comprehensive Control of Vibration Isolation System with Flexible Foundation

The paper analyzes the dynamic relation of asymmetric multi-supported vibration isolation system with flexible foundation, establishes the comprehensive model of passive control and positive control system by using the effective matrix analysis method, analyzes the transmission mechanism and characteristic of vibrational power flow in the flexible vibration isolation system. 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 puts forward the measure to reduce vibration energy transmission.
