Abstract:The vertical stiffness and grounding characteristics of a non-pneumatic mechanical elastic wheel under the conditions of different camber angle were studied to improve the vehicle driving safety. In considering the laminated structure of flexible tire body, a three-dimensional finite element model (FEM) of mechanical elastic wheel was established, which includes the incompressibility of rubber material, large deformation and contact nonlinearity. Static loading tests were conducted to validate the accuracy and reliability of the FEM. The simulated results of the influence of camber angle on vertical stiffness, contact patch and pressure distribution are compared with experimental results and discussed in detail. The results show that the vertical stiffness decreases with the increase in camber angle; the pressure is mainly concentrated in the shoulder of flexible tire body; and the uniformity of the pressure distribution becomes worse as the camber angle increases. The research provides a theoretical reference for the study on the camber performance, the uneven wear of tread and the structure optimization. © 2018Y, Editorial Board of Acta Armamentarii.
