摘要
在恶劣道路激励下，较大的往复动应力促使了重型汽车车架疲劳现象的产生．本文通过对某重型汽车车架动态应变响应信号的数理统计分析，根据结构关键测点动应力大于３值的概率，提出了一种结构动强度分析的简单方法．
Under the rough road exciting, the largedynamic stress will result in fatigue of the chassis.By the statistical analysis for the dynamic strainsignal of a heavy truck's chassis, a simple dynamicstrength analysis method t based on the 3 probability of the key measured points' dynamic stress, isput forward in this paper.
