摘要

基于疲劳寿命损伤理论,通过分析各级载荷对疲劳寿命的贡献,对零件损伤小的载荷,将其部分使用次数按其他载荷等级的频度分配。利用Ansys软件对蜗轮蜗杆进行动态分析,得到齿面接触应力结果;在n Code疲劳分析软件联合有限元分析结果与循环载荷时间历程,计算蜗轮蜗杆的疲劳损伤,通过试验进行验证。给出具体的计算方法,就蜗轮蜗杆的加速可靠性及可行性进行分析。

Abstract

Based on the fatigue life damage theory,the load contribution to the fatigue life was analyzed,then dispensed part frequency of small load to other load levels. The corresponding stress distribution was obtained using the software of ANSYS;the fatigue damage of worm gear was calculated by correlating results of ANSYS and the time history using the software of n Code,and compared with the experimental results. This paper presented specific calculation method,and analyzed reliability and feasibility of accelerated fatigue of worm and gear.
