讨论了减速器机匣安装边疲劳寿命分析的方法。提出了一种安装边载荷计算方法。采用半解析有限元法计算安装边的应力 ,然后采用局部应力应变法计算疲劳寿命。给出了两个算例 ,采用本文方法对一机匣试验件安装边的应力及疲劳寿命进行了计算并与试验结果进行了比较和分析。
Discusses the method of fatigue life analysis of reducer casing when mounting. A method to calculate the side load is proposed. The semi-analytical finite element method is used to calculate the stress of the mounting side, and then the fatigue life is calculated using the local stress-strain method. Two examples are given. The stress and fatigue life of the mounting side of a casing test piece are calculated and compared with the test results by this method.
