摘要
鉴于汽车座椅调角驱动器壳体是起着安装、承载和保护内部传动部件作用的重要零件,其结构强度的好坏直接影响着调角驱动器的技术性能及使用寿命,因此,需对汽车座椅调角驱动器壳体的结构可靠性进行有限元分析。以某企业的一款新型调角驱动器产品为研究对象,以壳体的最大应力小于135 MPa和最大变形量不大于1 mm为评价标准,综合运用NX10.0,ANSYS19.0等软件,在详细分析该壳体受力情况的基础上,确定模型的边界条件,完成了壳体的结构静力学分析,并得到了工作状态下壳体的应变云图和应力云图。有限元计算结果表明,该壳体的最大变形量为0.856893 mm,最大等效应力为116.269 MPa,均满足评价标准的要求。壳体的最大变形区域位于零件的右下侧部位,壳体的应力最大区域则位于壳盖顶面的中间部位以及边沿区域。可见,该壳体零件的强度、刚度均完全符合设计要求,所开发的新产品结构设计合理。
Considering that the shell of the automobile seat-angle adjustment driver is an important part which plays the role of installing,bearing and protecting the internal transmission components,the reliability of its structure directly affects the technical performance and service life of the angle adjustment driver,therefore,it is necessary to carry out a finite element analysis on the structural reliability of the automobile seat-angle adjustment driver.Taking a new type of angle adjustment driver product of a certain enterprise as the research object,and taking the maximum stress of the shell less than 135 MPa and the maximum deformation not more than 1 mm as the evaluation standard,on the basis of the detail force analysis of the shell,the boundary conditions of the model were determined,the static analysis of the shell was completed,and the overall deformation cloud map and equivalent stress cloud map of the shell were obtained based on the comprehensive use of software such as NX10.0,ANSYS19.0 and so on.The finite element calculation results show that the maximum deformation of the shell is 0.856893 mm,and the maximum equivalent stress is 116.269 MPa,which all meet the requirements of the evaluation standard.The maximum deformation area of the shell is located on the lower right side of the part,and the maximum stress area of the shell is located in the middle and edge areas of the top surface of the shell cover.It can be seen that the strength and stiffness of the shell parts fully meet the design requirements,and the developed new product has a reasonable design structure.
