在发动机气缸体的框架设计开发过程中,由于主轴承盖结构承载着曲柄连杆机构往复运动所施加的交变载荷,主轴承盖结构的疲劳强度直接影响着气缸体的使用寿命。本文阐述设计阶段通过模拟发动机实际工作状态,对零件进行疲劳安全性能的计算,以便有效地降低框架实际生产后裂纹、断裂等失效形式的发生。

In the development of frame design for cylinder block,the fatigue intensity of main bearing cap structure has affects on service life of cylinder block immediately,because main bearing cap structure supports the load brought by to-and-fro sport of winch connecting rod.The paper explains that simulation of the actual working condition of engine in design period and calculation of the fatigue security capability for parts in order to reduce the lapse form of crack and rupture after actual production.
