Driving Dynamics Modeling and Simulation of Wheeled Off-Road Vehicle
A multi-rigid body dynamics model of wheeled off-road vehicle was established considering the chassis suspension structure and the elastic characteristics of fire.The model was verified and improved by road-block shock test.Combined with the road roughness of level B ~ G,the driving dynamics model was built,and the vehicle acceleration and the pitch attitude under different vehicle speeds and different random road excitations were simulated.The simulation and test results show that the dynamics models have higher credibility.
