A lumped parameter model of a hydraulic engine mount (HEM ) is built in order to analyze the low-frequency dynamic responses of the engine of a car. MATLAB code is used and the experiment is done for dynamic characteristics analysis. Both results are mutually in a good agreement. It shows that the HEM model can be used to analyze the dynamic response of the engine mount precisely. The full-vehicle dynamic model is built by ADAMS/CAR. Numerical simulations of the full-vehicle’s dynamic performance are carried out for the HEM and the rubber mount respectively. And their vibration isolation performances are compared mutually. The results show that the former have a better vibration isolation performance than the latter.
