摘要
针对某汽车的一挡结合齿圈出现的疲劳失效问题,从制造工艺和结构入手,进行了结合齿圈的改进设计。采用SolidWorks Simulation并进行了静力学和疲劳有限元分析。结果表明:采用整体锻压工艺设计的一端封闭形式的结合齿圈相对于原单独锻压焊接形式的结合齿圈,其最大应力下降明显,疲劳寿命得到显著提高,较好地解决了结合齿圈的疲劳失效问题。
Changes in manufacturing process and construction to improve design were done to solve the problem of fatigue failure occurred in the combined ring gear,that was combined with the first gear of a kind car in this paper. The previous one was welded with the first gear while the improved one,closed at one end,was whole forged with the first gear. Finite element analysis was applied to static analysis and fatigue strength analysis of these gears. Results showed that there was an apparent decline on the maximum stress of the improved one,that could increase the life of the combined ring gear.
