英文摘要：

Based on the experiments on dynamic characteristics of the rubber spring, this paper established a nonlinear rubber spring model. The simulation results show good agreement with the measurement results. So the proposed model can represent the mechanical behavior of the rubber spring. This provides a basis for performing dynamic analysis of the vehicle suspension system and parameter optimization of the rubber spring.
