基于ABAQUS的万向节淬火应力有限元分析与优化设计

Finite Element Analysis and Optimal Design of Quench Stress of Universal Joint Based on ABAQUS

利用有限元分析软件对万向节球笼壳体的最大应力位置和应力分布规律、工件表面淬硬层残余应力随温度的变化、工件表面淬硬层残余应力对万向节球笼壳体工作应力的影响进行了分析。在分析的基础上,提出了万向节的设计原则。通过优化壳体的厚度等参数和淬硬层厚度,减轻了壳体的质量,提高了壳体的性能。

With FE analysis software, location with the maximum stress and stress distribution rule of universal joint ball cage, the residual stress of the quench-hardened case of the workpiece change with temperature as well as influence of the residual stress on working stress of universal joint ball cage are analyzed. On the basis of the analysis, the design principle for universal joint is presented. By optimizing thickness of ball cage housing and quench-hardened case, housing mass is reduced and performance is improved.
