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.
