摘　　要：悬架综合性能和整车操纵稳定性及乘坐舒适度密切相关。针对某款国产车型的悬架综合性能验证,借助Adams/Car软件模块,建立了具有柔性稳定杆子系统的前悬架模型和具有柔性体扭力梁子系统的后悬架模型,形成刚柔耦合的整车悬架系统模型。将车轮位移和受力约束分别施加在悬架系统上,进行动力学及弹性运动学分析,得到不同特性下的车轮定位参数。仿真结果显示,仿真数值和实车K&C试验数据基本一致,悬架综合性能相比于对标车车型更加优化;同时,进一步开展稳态回转路试,从侧倾加速度、不足转向度和车厢侧倾度三个维度,验证整车路试稳态特性满足设计要求,具备良好的运动特性。The comprehensive performance of suspension directly affects the handling stability and riding comfort of the vehicle. The suspension performance of a domestic vehicle was verified. By using ADAMS/car software, the front suspension model with flexible stabilizer bar subsystem and the rear suspension model with flexible torsion beam subsystem are established to form the suspension system of vehicle with rigid-flexible coupling model. The displacement and force were applied to the suspension system respectively. The dynamic and elastic kinematics analysis were carried out, and the wheel alignment parameters under different characteristics were obtained. The simulation results show that the simulation values were basically consistent with the real vehicle K&C test data. The comprehensive performance of the suspension of this model was more optimized than that of the standard model. At the same time, through the rolling acceleration, understeering and car rolling three aspects, the steady-state rotary road test was conducted to further verify that the steady-state characteristics of the vehicle meet the design requirements and have good motion characteristics.
