The Harmonic Vibration Isolation and Parameter Optimization on Double Layer Vibration Isolation System of the Automobile

The harmonic vibration isolation is studied deeply on double vibration is olation system of the automobile.The model of the vertical direction is established for this system which includes Ruzicka vibration isolation implement.The absolute transmissibility is deduces,.and the influence on the transmissibility is analyzed for motivate parameter of this system.The parameter is optimized and the optimal damping ratio is confirming of this system by MATLAB software.The conclusion is obtained by analysis.This system which includes Ruzicka vibration isolation implement is better than the simple double vibration isolation system.
