| 摘 要： | 固定式刚度测试仪是针对大型汽车覆盖件刚度测量的高精度测量仪器.通过确定相关参数、建立机架有限元模型,运用有限元软件ANSYS对固定式刚度测试仪初定方案进行了结构分析,并通过查看锡青铜衬套应力云图,找出初定方案所存在的问题;在此基础上对结构进行优化并进行有限元分析,通过对比分析结果,确定了固定式刚度测试仪优化后结构的合理性.优化方案解决了初定方案所存在的问题,减小了两边立导柱和衬套之间的摩擦力,改善了摩擦力的不均衡性,使横梁的升降更加平稳.

| Abstract: | The fixed stiffness tester is a high-precision measuring instruments for large automotive panel stiffness measuring.Through defining relevant parameters,establishing finite element model of the frame,an initial program for fixed stiffness tester's structure is analyzed by using finite element software ANSYS,in which problems available could be found out by viewing the stress contour figure of the bronze bush;on the basis of the initial program,the optimization of structure and finite element analysis are co... |
