In order to realize the localization of high speed train key components,combined with the performance requirements that high-speed train on the shock absorber and operating environment, an innovative design is developed for the piston structure of the CRH380BL secondary lateral damper. Three-dimensional design software SolidWorks is used to complete the new piston structure design of damper. The new type piston structure has better working characteristics and process controllability. In the MSC. Easy5 environment, hydraulic control model of shock absorber is established. Through the simulation test of shock absorber performance, the structural parameters preferred of new type piston are completed. The test results and simulation data are compared and analyzed, and the simulation results are consistent with the test results. The results show that using the basic parameters such as the compression force, the restoring force and the asymmetric rate of shock absorber of new type piston structure can satisfy the technical requirements for hydraulic damper of EMU. Hydraulic model of shock absorber has good simulation accuracy. The innovative design of hydraulic shock absorber piston meets design and work requirements.
