摘要

利用三维软件Solidworks与有限元分析软件Ansys Workbench联合,对三叉杆滑块式万向联轴器建模,然后整体进行静力学分析和疲劳寿命分析,得到联轴器等效应力分布云图及疲劳寿命云图,根据分析得出其疲劳破坏点位置。三叉杆根部采用不同过渡圆角尺寸的疲劳分析结果表明,不同尺寸的圆角倒角尺寸有着不同的寿命,改变联轴器应力集中部位的圆角、倒角尺寸,可以有效避免不合理的寿命分布,提高联轴器的疲劳寿命。

Abstract

Static analysis and fatigue analysis of the tripod sliding universal joint was conducted by Solidworks and ANSYS Workbench software. The equivalent stress distribution contour plots and fatigue life nephogram of the tripod joint was obtained, though which the fatigue damage points were found. Different sizes of fillet chamfer sizes have different lifetimes, fatigue analysis of the tripod joint with different transition arc radius indicated changing effective stress concentration size could avoid its unreasonable life distribution and improve its fatigue life.
