摘要
在对牵引拉杆进行静强度分析基础上,运用ANSYS/FE-SAFE软件分析并计算其疲劳寿命;基于应力-寿命模型P-S-N曲线,以无故障行驶里程数为可靠性评价指标,计算牵引拉杆的中位寿命和可靠度为99%下的寿命,为车辆安全可靠运行提供科学依据.
The static strength analysis is carried out on the traction rod,and its fatigue life is analyzed by using ANSYS / FE-SAFE software. According to stress and fatigue life model P-S-N curve and taking non-failure mileage as reliability evaluation index,the median life and 99% reliability life are calculated. The method will provide a scientific basis of safe and reliable operation of the vehicle.
