Abstract:
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.
