Abstract:To study the camber performance of the mechanical elastic wheel, in this paper, we analyzed the wheel suspension structure and bearing characteristics and established a brush theory model for the pure camber mechanical properties of mechanical elastic wheel based on the hypothesis that the tire body is rigid. The functions of the lateral force, aligning moment and overturning moments in the pure camber condition were deduced. A three-dimensional finite element model (FEM) of the mechanical elastic wheel, which contains nonlinearities such as the hyperelastic characteristics of rubber and large contact deformation, was established by ABAQUS. And the reliability of the simulation model was validated by the vertical loading test. By comparing and analyzing the simulation results and the theoretical values of camber performance, it indicates that the camber brush model of the mechanical elastic wheel has good accuracy. These research results provide theoretical guidance for modeling the mechanical characteristic of the mechanical elastic wheel under the combined conditions of camber, longitudinal slip, and sideslip. © 2018, Editorial Department of Journal of HEU.
