摘要:
 介绍了强度评定准则FKM 的主要内容,引用FKM 局部应力法对抗侧滚扭杆的疲劳强度进行评定,并与Fe-safe 的疲劳强度评定结果进行对比。对比结果表明:两者的评定结果一致且FKM 准则更加保守,抗侧滚扭杆的疲劳强度满足使用要求。由FKM 准则得出的扭杆各应力分量疲劳损伤度表明:扭杆剪切应力对扭杆的疲劳损伤最大,弯曲正应力次之。
Abstract:
 The main content of FKM guideline for assessing the fatigue strength was introduced, and the fatigue strength of anti-roll torsion bar was assessed by referencing FKM local stress approach, which was compared with Fe-safe. The result showed that: both of the evaluation results were consistent and the FKM guideline was more conservative, the fatigue strength of anti-roll torsion bar could meet the requirements. The fatigue damage degree of each stress component of the torsion bar obtained by the FKM guideline showed that the maximum fatigue damage of torsion bar was from the torsion bar shear stress, and the bending normal stress was the second one.
