中文摘要：

针对用传统材料力学分析难以精确获得减振器工作状态下伸张阀和压缩阀弹簧阀片组的应力和应变值的难题，采用有限元法对其工作状态下的压力分布进行研究。根据减振器工作状态下弹簧阀片组的内部受力关系，基于有限元软件ANSYS，通过创建弹簧阀片之间的接触对来模拟弹簧阀片之间的约束关系。为准确分析阀片组的受力关系，建立了伸张阀和压缩阀的力学模型，并结合减振器工作特性曲线定义伸张阀和压缩阀的载荷。通过对伸张阀和压缩阀的强度和刚度进行分析，得到了工作状态下减振器伸张阀和压缩阀的应力、应变分布云图，为后续优化设计提供依据。

英文摘要：

According to difficult to accurately obtain stress and strain value of rebound valve and compression valve on shock absorber in working status by using traditional materials mechanics, finite element analysis was applied in the research. Constraint relation among spring valve plates on shock absorber was simulated by creating contact pair based on ANSYS according to internal force relations of spring valve plates group on shock absorber in working status. The mechanical models of rebound valve and compression valve were established in order to accurately analyze force relation of the valve plates group. The loads of rebound valve and compression valve were defined by combining performance curve of shock absorber. The stress and strain distribution of rebound valve and compression valve were obtained by analysis of strength and rigidity when shock absorber was in working status. It provides basis for subsequent optimization design.
