Simulation and experimental study of semi-active control hydraulic mount

A new semi-active controlled hydraulic mount was developed. Its dynamic characteristics can be improved by adjusting the cross-section of its inertia channel. Theoretical analysis and system test show that the design of the semi-active absorber is reasonable and effective. The dynamic stiffness and damping performance of the hydraulic mount could be changed through adjusting the cross-sectional area of the inertia channel. Test results on a double mass system show that the optimum vibration isolation effect could be obtained at different exciting frequencies by adjusting the cross-section area of inertia channel.
