摘　　要：对连杆螺栓受力进行了研究,利用ANSYS对螺栓进行静力学分析,得出螺栓的应力分布状况。对连杆螺栓断裂事故进行了分析,得出可能造成螺栓断裂的原因;利用Miner疲劳损伤理论和ANSYS软件,分别对连杆螺栓进行疲劳寿命计算,预估螺栓的使用寿命。The force of the connecting rod bohs is researched in the paper. Using ANSYS software, static analysis of connecting rod bolts is calculated. And the stress distribution of connecting rod bolts is got from ANSYS. The accident that the connecting rod bolts broken is analyzed and the reason for the bolt fracture is obtained. Using Miner Fatigue Damage Theory and ANSYS software, the fatigue life of connecting rod bolt is calculated and the using life of bolt is estimated.

关 键 词：连杆螺栓 断裂分析 强度分析 疲劳计算
