摘　　要：文章以某型柴油机曲轴为例进行分析,首先对柴油机工作过程进行估算,然后运用有限元分析法,得出柴油机曲轴在4个冲程工作过程中的受力情况和曲轴动力数据,进而研究柴油机曲轴发生裂纹或者断裂失效的位置分布规律,用以指导曲轴设计者对关键部位、油孔位置、倒角要求等方面进行优化,指导柴油机维修人员对曲轴的关键部位进行重点维修保养。Taking a military diesel engine crankshaft as example, the distribution rule for crankshaft~ fracture is researched by getting the force condition in the working course of the four strokes and carankshaft~ dynamic data with estimation and finite element analysis, with which the key position, oil-pore location and angle grinding are optimized and the key parts are maintained.

关 键 词：柴油机 曲轴 有限元法
