摘　　要：1115柴油机是在1110柴油机基础上扩缸而成的,由于发动机动力负荷增加,经常出现曲轴或机体断裂现象。为此对其进行了针对性的有限元分析和设计改进。通过改进不仅强度增加、可靠性提高,而且质量减轻,取得了双重效果。1115 diesel engine is modified on the basis of 1110 engine by enlarging its cylinder diameter. Due to increasing of the engine power load, the crankshaft and the engine body often break, for which we carried out relative finite element analysis and optimal design. After modification, its strength and reliability is improved, and its weight is reduced.
