摘　　要：介绍了根据整车参数,在满足悬架性能的基础上,匹配设计悬架导向机构硬点的方法。以国内一款正在研发的电动小车为例,计算了与小车相匹配的双横臂独立悬架导向机构硬点位置坐标,在ADAMS/CAR下建立了小车悬架模型,仿真结果表明初次匹配的悬架导向机构基本合理;并通过ADAMS/INSIGHT,对悬架定位参数的影响因子进行了分析,重新匹配计算了硬点坐标,仿真验证重新匹配的机构更能满足设计要求。研究结果为悬架设计的研究提供了参考。Introducing a method to matching hard points on the guidance organization of double wishbone suspension system,based on vehicle parameter,with requirements for suspension performance fulfilled.By applying this method to electrical vehicle,the hard points of guidance organization are calculated,and the double wishbone suspension model was built with ADAMS/CAR.According to simulation results,the first matching organization meets the requirements of the design fundamentally.Through the ADAMS/INSIGHT,doing a deeper research on the influence factors to alignment parameters,and the new hard points are calculated then.The second matching organization obtains better performance.The investigation provides an important reference for the suspension design.
