Abstract:Mechanical elastic wheel (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 ME-wheel, experimental research on mechanics characteristics of ME-wheel under steady-state cornering conditions are carried out. The test of steady-state cornering properties of ME-wheel at different experimental parameter conditions is conducted by test bench for dynamic mechanical properties of tyre. Cornering property curves are 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 are extracted and the effect of different experimental parameters (including vertical load, friction coefficient, and speed) on cornering properties of ME-wheel is contrastively analyzed. The proposed research can provide certain reference to facilitate structure parameters and cornering properties optimizing process of ME-wheel. © 2017, Editorial Department of Transactions of NUAA.
