摘　　要：橡胶弹簧的疲劳寿命直接反映出橡胶悬架的疲劳寿命。介绍了一种预测橡胶弹簧疲劳寿命的试验方法。该方法通过试车场道路试验里程对试验室台架疲劳试验次数进行标定,根据橡胶弹簧的刚度损失率,分析出台架疲劳试验次数与道路试验里程之间的关系,进而根据对橡胶弹簧台架疲劳试验效果的评价来预测其疲劳寿命。通过试验验证了该预测方法的可行性。Fatigue life of rubber spring directly reflects that of rubber suspension. A test method to predicate fatigue life of rubber spring is introduced in this article. In this method, number of laboratory bench test is calibrated by road test mileage on proving ground. According to the loss rate of stiffness of rubber spring, the relationship between the bench test number and road test mileage is analyzed and the fatigue life of rubber spring is predicated by evaluation of bench test results of rubber spring. Feasibility of this predication method is proved by test.
