Abstract:Theoretical and experimental investigation on mechanical characteristics of steady-state cornering conditions of mechanical elastic wheel was carried out in order to master cornering properties of mechanical elastic wheel. The theoretical modeling process of steady-state cornering with small and large side-slip angle was discussed by fully considering the structure characteristics of mechanical elastic wheel and using the basic theory of brush model. Experimental analysis on steady-state cornering properties of mechanical elastic wheel was carried out by using tire dynamic mechanical properties test bench, and the relationship curves of the lateral force, aligning torque and side-slip angle were obtained. Simulation results of theoretical model were compared with the experimental data. Results show that the established theoretical model of steady-state cornering has high accuracy, and can express mechanical characteristics of steady-state cornering properties of mechanical elastic wheel. This investigation provides certain reference for the improvement of wheel structure and cornering properties. © 2017, Zhejiang University Press. All right reserved.
