Modeling and Simulation of Hydraulic Mount Dynamic

This paper basing on the linear model used the switched system theory and started with the actual physical work process of the decoupling disc hydraulic suspension to divide the vibration motion state into two kinds of work modes, four kinds of basic working process, make switched strategy pattern between the work modes and establish the switched system model of the decoupling disc hydraulic mount. Finally, the validity of the model was verified by comparing the decoupling disc hydraulic mount dynamic characteristics test with the simulation results of the model.
