汽车零部件加速疲劳试验方法

在探讨了结构零部件和加速疲劳试验准则的基础上，阐述了各种常见的加速疲劳试验方法的适用范围，提出了并初中了一种简单的“非线性强化载荷谱法”，试验证明，该方法不仅可以达到令人满意的加速效果，而且还极好地保持了失效机理的不变性。

Method for Speeding Fatigue Test of Motor Vehicle Components

On the basis of exploration of the criterion of speeding fatigue test for structural components,the article sets forth the adaptive area of various common methods for speeding the fatigue test. A simple non-linear intensified spectrum method is raised and put into practice. The test indicates that the method not only can reach to a satisfactory speeding effect,but also can keep very well the failure mechanism unchangeableness.
