某型中速柴油机活塞销强度及寿命分析

摘要

我们结合工程实例, 利用ANSA/ABAQUS/FEMFAT等有限元计算软件, 对某中速柴油机活塞销强度和寿命进行计算, 并对比分析, 确定其应力分布情况, 并对其疲劳寿命进行分析预测, 对后续设计改进提供数据分析支持.%Combining with engineering examples, the strength and life of piston pin of a medium-speed diesel engine are calculated by using finite element software such as ANSA/BAQUS/FEMFAT, and the stress distribution is determined and its fatigue life is analyzed and predicted, provide data analysis support for subsequent design improvements.
