Abstract:
ME-wheel is a new type of non-inflatable safety tyre, and the structure is significantly different from traditional pneumatic tyre. In order to investigate cornering properties of mechanical elastic wheel (ME-wheel), experimental research on mechanics characteristics of ME-wheel under steady-state cornering conditions were carried out. The test of steady-state cornering properties of ME-wheel at different experimental parameters conditions was conducted by test bench about dynamic mechanical properties of tyre. Cornering properties curves were used to analyze the steady-state cornering properties of ME-wheel, namely the variation tendency of lateral force or aligning torque with the increase of side-slip angle. Moreover, evaluation indexes for cornering properties of ME-wheel were picked up and effect of different experimental parameters (including vertical load, friction coefficient, and speed) on cornering properties of ME-wheel was contrastively analyzed. The research in this paper could provide certain reference to facilitate structure parameters and cornering properties optimizing process of ME-wheel.
