| 摘 要： | 以往对发动机曲轴结构强度的研究，其基本出发点都是安全系数法，因此不能定量地反映曲轴安全可靠的程度。运用概率统计方法，对曲轴弯曲疲劳强度进行了可靠性分析和可靠度计算，可靠度指标能够定量地反映曲轴的安全可靠程度。

| Abstract: | Formerly the fundamental consideration of research work of constructional strength of engine crankshaft is from the sarting point of safety factor,which is not able to quantitatively reflect the degree of reliability of crankshaft safety. when analysis of reliability and calculation of reliability degree of crankshaft bending fatigue strength are carried out by means of probability statistics,index of the reliability degree can quantitatively reflect the degree of reliabi-lity of crankshaft safety. |
