摘　　要：在ADAMS/Car下,基于'概念悬架'模块搭建了14自由度整车动力学模型,模型的动力学仿真结果与实车试验数据有较好的一致性。利用该模型分析了前悬架中的各项特性对该车不足转向度的贡献;该车的前悬架的C特性对不足转向特性的影响最为突出。最后文章进行了前悬架K&C特性改变对整车操纵稳定性影响的分析,介绍了一种由整车性能分解到悬架性能的思路。A 14-DOF vehicle dynamics model was built in ADAMS/Car based on the conceptual suspension module.The dynamic simulation results using the model were in good agreement with those of road test.The effect of the properties of the front suspension of the understeer rate was analyzed using the model,and it was found that the C property of the front suspension shows larger effect on the vehicle understeer.The effects of the KC properties of the front suspension on the vehicle handling stability were analyzed,introducing a train of thought to dissolve the whole vehicle performance to the suspension KC properties.
