摘要
为了进一步改善汽车悬架的运动学性能,对汽车前独立悬架进行优化设计。首先,利用ADAMS/Car模块分别建立汽车麦弗逊前独立悬架和双横臂前独立悬架模型,并针对两类悬架设计双轮平行跳动和异向跳动仿真试验;然后,在ADAMS/Insight模块中选取部分硬点坐标作为试验变量,进行灵敏度分析;最后,调整硬点坐标,对前轮定位参数进行优化设计。在两类悬架的双轮平行跳动和异向跳动试验中,悬架定位参数变动范围及变化量基本一致,前轮前束角、前轮外倾角、主销后倾角和主销内倾角均达到理想变化范围,其中双横臂独立悬架优化效果最为明显。
In order to improve the kinematics performance of the suspension,optimization design of front independent suspension of vehicle is studied in this paper. First,ADAMS/Car module is used to build the McPherson front independent suspension model and the double wishbone front independent suspension model,and two kinds of suspension are simulated by parallel and isotropic running of two wheels. Then some hard point coordinates in ADAMS/Insight module as test variables are selected for sensitivity analysis. Finally,the hard point coordinates are adjusted to optimize the front wheel positioning parameters. The results show that the range and amount of variation of the positioning parameters of the two wheels of McPherson independent suspension and double wishbone independent suspension are basically the same. The front wheel camber angle,toe angle,front wheel kingpin caster angle and kingpin inclination angle have reached the ideal range,and the optimal effect of double wishbone independent suspension is the most obvious.
