Abstract
Multi-axle trucks are prone to rollover in their driving due to its giant size, larger mass and higher gravity center. Here, the rollover model of multi-axle trucks was studied. A 3-DOF nonlinear rollover model for them was built considering characteristics of multi-axis steering, tire nonlinearity and suspension nonlinearity. Real vehicle tests were conducted to verify the correctness of the model. Effects of the main nonlinear parameters in the model on the vehicle's dynamic responses were studied based on the nonlinear model. The results showed that the lateral leaning stiffness of tire has little effect on the vehicle attitudes within a certain range; the rigidity of hydro-pneumatic spring of suspension has a significant influence on the vehicle roll angle, while it has little effect on the lateral acceleration of the vehicle.
