摘　　要：应用整车道路模拟试验进行悬架系统的耐久性验证成本高,而在试车场强化试验周期较长。针对该问题,提出一种悬架系统道路模拟试验方法。通过对悬架系统道路模拟试验的固定反力式装置进行设计,结合某乘用车后悬架系统,利用新建立的悬架道路模拟试验台成功进行了道路模拟试验。达到缩短悬架系统的验证周期,节约试验成本的目的。In view of the high cost of the application of the whole vehicle road simulation test in the durability verification of suspension system,and the long period of strenuous test in the test field,a road simulation test method of the suspension system is proposed.Through the design of the fixed reaction device for the road simulation test of the suspension system,combined with the rear suspension system of a passenger car,the road simulation test is successfully carried out by using the newly established road simulation test-bench of the suspension system.The verification cycle of suspension system is shortened and the test cost is saved.
