The mathematical model of the metal-rubber shock absorber is first established. The overall optimization of the metal-rubber shock absorber is carried out using the genetic algorithm. The optimization result is determined by combining with the finite element analysis, the experimental verification is finally carried out. The results show that the stiffness of the optimized metal-rubber shock absorber is significantly enhanced, and the compressive capacity of the metal-rubber shock absorber is also improved to a certain extent. There is a certain error between the simulation results and the experimental results, but the optimized metal-rubber shock absorber meets the working requirements of the carrier vehicle, so the optimization design of the shock absorber has achieved the expected goal.
