Simulation analysis of an off-road SUV for steadystate performance

Steady-state performance is an important part of vehicle handling stability, and is significant to steering safety. In this paper, a steady-state simulation model of an off-road SUV is established in ADAMS/CAR. The curve of steering wheel angle changing with lateral acceleration on a constant radius turn, coincides with the result of the bicycle model. According to GB/T 6323.6-94, steady-state cornering simulation analysis is carried out by this model, and the result shows that the vehicle has good steady-state performance.
