Finite Element Strength Analysis and Optimization of Actuator for Automobile Seats Height Adjuster

针对汽车座椅抬高调节驱动器输出扭矩偏低的问题,基于ANSYS Workbench平台进行有限元强度分析,根据结构应力分布特点,提出了提高材料强度和局部尺寸优化的方案。有限元计算结果表明:优化后结构的输出扭矩增大了70N.m,满足了设计需求,同时试验结果也进一步验证了有限元分析的正确性。

In order to solve the problem of low output torque of actuator for automobile seats height adjuster,finite element strength analysis(FEA)was carried out based on ANSYS Workbench,and according to the characteristics of structural stress distribution,measures for improving material strength and local size optimization are proposed.The finite element calculation results show that the output torque of the optimized structure increases by 70N.m,which meets the design requirements.The experimental results further verify the correctness of finite element analysis.
