【摘要】 基于概率论和数理统计的理论，通过试验数据对发动机缸壁的耐磨寿命及可靠性问题进行了定量的研究。根据磨损量及耐磨寿命分布函数，确定可靠度函数方程，可以预测零件在一定时间内或给定允许磨损等条件下的耐磨寿命及可靠度。更多还原

【Abstract】 Based on the theories of probability and mathmatical statistics, the quantificational research to the anti-wear life and reliability of cylinder wall of the engine has been carried out. With the wear off quantity and the distributional function of anti-wear life, the function equation of reliability can be determined and the reliability and anti-wear life within a certain time or allowable wear off quantity could be Predicted.更多还原
