摘　　要：介绍了根据整车参数,在满足整车性能和麦弗逊悬架运动特性的基础上,根据悬架结构之间的几何关系,匹配设计计算悬架硬点位置、刚度和阻尼的方法.以国内一款正在研发的电动小车为例,设计了与小车相匹配的前麦弗逊悬架结构,并在ADAMS/CAR下建立悬架模型.仿真结果表明匹配设计的麦弗逊悬架基本满足要求.研究结果为悬架设计的研究提供了参考.This paper introduced a method to match hard points, rigidity and damping on Macpherson suspen- sion system, based on vehicle parameter, with requirements for suspension perfomance fulfilled. By applying this method to electrical vehicle, the Macpherson suspension structure is calculated, and suspension model was built with ADAMS/CAR. According to simulation results, this matching Macpherson suspension can meet the need of the design fundamentally. The investigation provides an important reference for the suspension design.
