为了提高汽车座椅工位器具的可靠性，对汽车座椅工位器具的动力学特性进行了研究。采用ANSYS有限元分析软件模拟的方法，得到了汽车座椅工位器具的模态分析、谐响应分析以及线性曲屈分析结果，从而为工位器具的振动特性分析、振动故障诊断和预报以及结构动力特性的优化设计提供依据。

Dynamic characteristics of working position apparatus were studied to improve their reliability. Simulation was cared out using finite element analysis software ANSYS. The results of modal analysis, harmonic response analysis and that of linear buckling analysis were obtained. The purpose was to provide reference for vibration characteristic analysis, diagnosis and forecast of vibration fault as well as optimization design of the structure's dynamic characteristics.
