| 摘 要： | 本文对车辆悬挂系统扭杆弹簧的寿命作了统计分析,得到服从形状参数m=1.5～2.0的威布尔分布.论证了把可靠度R(t)=0.9的工作寿命作为规范中所规定的额定寿命值的合理性,同时对影响其寿命的若干因素进行了讨论.

| Abstract: | This paper presents the statistics analysis result for the torsion bar spring's life of automotive suspension systems,and comes to the conclusion that it obeys Weibull distribution which has the shape parameter m=1. 5~2. 0. At the same time the paper demonstrates the reasonableness that the work life which the Relibility is R(t) = 0. 9 is regarded as the specified life,and discusses some factors which affect its life. |
