基于威布尔分析的钢车轮弯曲疲劳寿命改善提升

Steel Wheel Rotary Bending Fatigue Life Improvement Based on Weibull Analysis

对钢车轮开发过程中弯曲耐久的试验结果进行威布尔计算分析,针对威布尔计算结果小即可靠性较低的情况进行分析,找到提升钢车轮弯曲耐久寿命影响的因素,并针对该因素进行改善,提高了威布尔F(t)=5%的分析结果,为汽车零部件底盘产品的疲劳寿命提升提供了参考。

According to steel wheel actual part test result during the development phase,the Weibull analysis for the result was carried out.The analysis results of Weibull calculation results with low reliability,and the factors that improved the bending fatigue life of steel wheels were found and improved.The analysis results of Weibull F(t)=5%is improved,which provides a reference for the fatigue life improvement of automotive parts chassis products.
