Abstract

Vehicle durability test is an effective means to evaluate the reliability of key system components. In view of the problems existing in the traditional vehicle durability test method in the vehicle proving ground, a user road load spectrum related design method of vehicle proving ground durability specification is proposed in this study. This method takes the user’s usage into account. Based on the principle that the road damage of users is equivalent to the road damage of proving ground, the load spectrum of users’ road and strengthened road of proving ground is collected by a certain vehicle. The load distribution matrix is obtained by rain flow counting method. Finally, according to the mathematical model of user association, the cycle times of proving ground strengthening road under the condition of equivalent load spectrum of rain flow matrix between user and proving ground are optimized. The strengthening coefficient of proving ground road surface and the durability test specification of vehicle proving ground related to user are obtained.

基于用户道路荷载谱的车辆试验场耐久性分析与试验研究

车辆耐久性试验是评估关键系统部件可靠性的有效手段。针对车辆试验场传统车辆耐久性试验方法存在的问题，提出了一种与用户道路荷载谱相关的车辆试验场耐久性规范设计方法。这种方法考虑了用户的使用情况。根据用户道路毁损等同于试验场道路毁损的原则，由某一车辆采集用户道路和试验场加固道路的荷载谱。采用雨流计数法得到荷载分布矩阵。最后，根据用户关联数学模型，优化了用户与试验场之间雨流矩阵等效载荷谱条件下的试验场加固路循环次数。得到了与用户相关的试验场路面强化系数和车辆试验场耐久性试验规范。
