The rubber mount components in suspension system have great influence on ride comfort of automobile. Based on the complex stiffness model and equivalent model of shock absorber rubber mount, the suspension system model with 2DOF including rubber mount components are established by using virtual coordinate. The influences of the stiffness of rubber mount component on the responses of suspension are analyzed in frequency and time domains. The results show that proper stiffness of rubber mount can decrease the acceleration of body by about 20% and dynamic load of tire by about 30% in the frequency range from 5 to 12 Hz compared with that without rubber mount. In addition, the stiffness of rubber mount component leads to lag acceleration of body and higher nature frequency of wheel.
