查询词典 fatigue curve

According to the Miner damage cumulative the fatigue life of torsion bar is analyzed and predicted based on two equivalent stress amending means Goodman and Gerber, combined with vehicle's driving environment, allocated proportion of driving load cases and material characteristic curve of torsion bar. The computational results indicate that Goodman is more conservative than Gerber and the difference between the predicted results is about seven times.

依据Miner线性损伤累积理论，结合车辆行驶环境和行驶工况的分配比例和扭杆弹簧材料特性曲线，采用Goodman法和Gerber法2种等效应力修正方法，对扭杆弹簧的疲劳寿命进行分析和预测，其计算结果表明Goodman法比Gerber法保守，两者之间的预测结果相差约7倍。
