Abstract：In order to lengthen the life span of four-level-damping adjustable hydraulic shock absorber,the optimization design of the shock absorber was carried out by simulation technology.Its simulation model was established,the fluid dynamics simulation of valve was caried out by ICEM CFD pretreatment software and ANSYS Fluent fluid analysis software in order to obtain the stress and internal fluid flowing speed data of the valve under the corresponding piston movement speed.The optimization design of changing the non-step symmetrical through hole of piston hole of shock absorber to shoulder hole in order to increase the flowing area of fluid was proposed.The performance tested was made in the characteristics of damping,reactive power and speed.The result showed that the improved shock absorber improved in every aspect and could lengthen the life span,which verified the feasibility of the optimization design.
