为了准确分析某越野车的动力学特性,该文基于有限元方法和多体动力学理论进行了刚柔耦合的整车建模和动力学仿真。考虑车架、悬架构件的实际变形,利用有限元软件Hyperworks对其进行柔性化处理,在ADAMS/Car中建立刚柔耦合的整车模型。根据国家标准GB/T 6323-94,对其进行蛇形和稳态回转仿真试验,并与多刚体模型的仿真结果进行对比。结果表明：结构零件变形对整车操纵稳定性仿真有一定影响,该车具有良好的操纵稳定性能。

In order to accurately analyze the dynamic characteristics of a certain off-road vehicle,this paper does a rigid-flexible coupling integral model and dynamic simulation based on the finite element method and multi-body dynamics theory. Considering their deformations,the control arms and frame are flexibly processed using the finite element software HyperWorks,and a rigid-flexible coupling whole vehicle model is built in ADAMS/Car. According to the national standard GB/T 6323-94,the snaking test and steady static circular test are carried out for a rigid-flexible coupling vehicle model. The model is compared with the simulation results of a rigid one. The results show that the deformations of flexible components affect the simulation results of the entire vehicle’s handling stability,and this vehicle has good handling stability.
