摘　　要：悬架横臂是双横臂独立悬架的重要构件.基于整车刚柔耦合模型,利用虚拟疲劳耐久性仿真分析方法,预测了悬架横臂在B级路面和某强化路面上的疲劳寿命,进而确定了汽车试验场典型强化路面的可靠性强化系数.结果表明,此种方法能够快速有效地预测零部件的疲劳寿命,并为产品的可靠性强化试验提供依据.The upper link ann is an important component in a double-wishbone independent suspension. Based on a rigid-flexible coupling model of a vehicle, and by using a simulation method for the virtual durability analysis, the fatigue life of the arm is predicted when the vehicle is running both on Class B road and an enhanced road, and the reliability enhancement coefficient of the enhanced road is obtained on an automobile proving ground. The results show that the above method can predict the fatigue life of the products quickly and efficiently, and provide a basis for the enhancement testing of their reliability.
