摘　　要：针对某车型,从理论上分析了车轮定位参数对整车操纵稳定性的影响,以及各车轮定位参数之间的关系。根据整车的数模及动力学参数,应用多体动力学软件ADAMS/Car建立了整车模型,并详细阐述了悬架的建模方法和步骤。采用国家标准:GB/T 6323.4-94对原整车模型和改进后的整车模型进行了回正性能仿真试验,最后分析并比较了两种模型的仿真结果,结果表明适当的加大主销后倾角能提高整车的转向回正性能和行驶稳定性能。该研究为整车的设计与开发提供了一种现代化方法。It analyzes vehicle handling stability influenced by the wheel alignment parameters as well as the relationship between them for a certain vehicle. Firstly, sets up entire virtual prototyping model of the bus and expounds the modeling method and steps of suspension using the multi-body dynamics software ADAMS/Car. Secondly, makes the steering return ability simulation test on the original vehicle model and the improves vehicle model on the basis of national standards GB/T 6323.4-94, thirdly, analyzes the results of the two models, which shows that increasing the kingpin caster appropriately can improve the performance of the whole vehicle steering return ability and traveling stability. It can provide a modem approach for the design and product development of the ftnished automobile.
