摘　　要：为克服汽车底盘零件台架试验载荷开发的盲目性,将采集到的实车路谱信号进行雨流统计、工况编制以及伪损伤计算后,转换为载荷块进行汽车控制臂台架疲劳试验验证。虚拟载荷块疲劳台架试验和实物载荷块疲劳台架试验结果表明:采用载荷块进行控制臂台架试验能准确再现路试的损伤分布情况,给底盘零件台架试验载荷的确定提供了一个全新的思路,并且能够达到加速试验周期和节省试验成本的效果。In order to solve the problem of blindness in the load development of automotive chassis component bench test,the block cycle load was converted to arm fatigue bench test after investigation of the rain-flow counting,duty cycle compiling and damage calculation of the collected road load spectrum on proving ground.The durability results of the virtual bench test and physical bench test of the control arm show that the damage distribution between the bench test and the proving ground is identical,which provides a new idea for the determination of the chassis structure bench test load.Besides,it can also accelerate the test period and decrease the test cost.
