摘　　要：利用有限元法,分析了某型工程车辆轮边减速器行星架的应力分布状况。引入"应力分类"的概念,对最大载荷下行星架应力场进行分析,采用"分析设计"准则进行了结构强度校核;利用专业疲劳分析软件nSoft,预测了行星架在存活率为50%和99%下的疲劳寿命,并确定了行星架的危险部位。计算结果表明该行星架强度和疲劳寿命满足设计要求。The stress distribution in the planet carrier of the hub redactor in a construction vehicle is analyzed using finite element method.By introducing the concept of ＇stress classification＇,the stress field of planet carrier under maximum load is analyzed,and strength check is carried out by adopting the ＇analytical design＇ criteria.The fatigue lives at 50% and 99% survival rates of planet carrier are forecasted using professional fatigue analysis code nSoft and the critical regions of the carrier are identified.The results show that the strength and fatigue life of planet carrier meet the design requirements.
