摘　　要：在汽车耐久性试验中,等幅试验是最快速、最简单的方法,而应用路谱的随机加载试验是最复杂的方法。本文应用局部应力—应变法、雨流统计、Neuber法则等损伤原则计算了某车型前鼓包处随机和等幅疲劳试验结果与汽车试验场之间的关系。计算结论:应用等幅试验和适当的疲劳分析也可以给出很有价值的结果。In the automobile durability test procedure, constant amplitude loading test is the fastest and simplest, and random loading test is the most complex. Based on the damage fatigue principle such as local stress-strain, rainflow statistics, Neuber rule, we obtained the correlation between the automobile proving ground and the testing result of random loading and constant amplitude fatigue test of vehicle front suspension. The result indicates that on the base of equal range test and relevant fatigue analysis we can also find valuable result under some condition.
