To enhance the damping characteristics of the dampers to better meet practical demands, this paper conducts an optimization analysis on the damping structural parameters. With an electromagnetic valve-type damper as research object, this paper analyzes its structure and working principle. Based on the mechanism of damping force generation, a damper simulation model is established in AMESim and compared with the bench test results, verifying the accuracy of the model. Utilizing the DOE module in AMESim, the influence degree of structural parameters on damping force is obtained, and the parameters that have a greater impact on the damping force are selected. Using the optimization module, the structural parameters are optimized with the target damping force curve as the goal. Simulation results show that compared to that before optimization, the maximum recoverable damping force increases by 34.61%, while the maximum compression damping force increases by 9.67%. The optimized damping characteristic curve is closer to the target curve, making it easier to meet the actual engineering requirements through parameter optimization.
