摘要
Abstract
The torsion fatigue life of crankshafts was analyzed by log-normal distribution function and Weibull distribution function.Estimated values of the fatigue life of crankshafts under different torque and survival probability were obtained by these two mathematical statistical models.Through the research and analysis on the difference between the estimated values of fatigue life obtained by these two mathematical statistical models,the best application interval of two mathematical statistical models was acquired.It could provide the reference to choose the reasonable mathematical statistical model for data processing in the subsequent torsion fatigue life analysis of crankshafts,and the more reliable analysis results could be gained.关键词
