Abstract:
An accurate vehicle model is essential for effectively representing vehicle behaviour, particularly in the study of ride and handling dynamics. This work focuses on developing a comprehensive vehicle model to analyse vehicle behaviour in various driving conditions. A 12-Degrees-Of-Freedom (DOF) vehicle model is derived, incorporating ride, handling, and tire dynamics. Two types of tire models—Linear and Nonlinear (Magic Formula)—are implemented in Simulink, and their performance is evaluated by comparing simulation results with ADAMS outputs. The tire model that best aligns with the ADAMS results is integrated into the 12-DOF vehicle model. All assumptions considered in the model development are detailed. The proposed vehicle model is validated using an instrumented vehicle under different steering inputs. The deviations between simulated and experimental results, particularly in yaw rate, lateral acceleration, roll angle, and individual tire slip angles, are analysed and discussed.
