摘　　要：减振器是悬挂系统的关键部件,而活塞又作为减振器的重要零件,直接影响着汽车减振性能的好坏。针对中兴新能源汽车减振器的活塞进行创新设计;分析了传统液压减振器的工作原理,运用SolidWorks进行了新型活塞的三维建模,建立了减振器双向流固耦合分析模型,导入ANSYS完成了减振器阻尼特性分析,并进行了试验验证。数据结果表明,相比于传统减振器活塞,新型减振器活塞的减振性能更优同时还减小了阀片的挠度变形,从而提高阀片的寿命;最后通过示功机完成试验,证明了减振器的双向流固耦合数值仿真具有一定的可靠性,新型减振器活塞的结构更优。The shock absorber is the core component of the suspension system,and the piston,as an important component of the shock absorber,directly affects the car′s damping performance.The innovative design of the piston of the shock absorber of ZTE's new energy vehicle is carried out;the working principle of the traditional hydraulic shock absorber is analyzed,the three-dimensional modeling of the new piston is carried out using SolidWorks,and the two-way fluid-structure coupling analysis model of the shock absorber is established and imported ANSYS completed the analysis of the damping characteristics of the shock absorber and carried out experimental verification.The data results show that compared with the traditional shock absorber piston,the new shock absorber piston has better damping performance and also reduces the bending deformation of the valve plate,thereby increasing the life of the valve plate;finally,the test is completed by the dynamometer.It is proved that the two-way fluid-solid coupling numerical simulation of the shock absorber has a certain degree of reliability,and the structure of the piston of the new shock absorber is better.
