摘　　要：为改善汽车振动特性,缩短开发周期并降低成本,以汽车双横臂悬架为研究对象,借助于ADAMS/CAR首先建立悬架参数模型,然后对悬架的平行轮跳动进行仿真分析,分析车轮定位参数,对不符合要求的车轮定位参数采用合理的优化算法,改变部分硬点坐标使之符合要求。为进一步分析悬架对整车振动特性的影响,最后对整车平顺性进行仿真分析,结果表明:优化后的悬架能够有效改善整车振动特性。In order to improve the vibration characteristics of the car,shorten the development cycles of the car and reduce the costs,the double wishbone suspension of car was studied with the help of ADAMS/CAR.Firstly,the parametric model of the suspension was established.Then,the runout of the parallel wheels of the suspension was simulated and analyzed.The wheel positioning parameters were analyzed and a reasonable optimization algorithm was adopted for the positioning parameters that do not meet the requirements,and some hard point coordinates were changed to make them meet the requirements.Finally,in order to further analyze the influence of the suspension on the vibration characteristics of the vehicle,the simulation analysis of the ride comfort of the vehicle was simulated.The results show that the optimized suspension can effectively improve the vibration characteristics of the vehicle.
