Abstract:
      Considering radial spoke thickness gradient variation，a non-pneumatic tire with honeycomb structure was designed，and the influence of spoke thickness gradient variation on the radial stiffness，lateral stiffness，longitudinal stiffness and torsional stiffness of the non-pneumatic tire with honeycomb structure was studied.The results indicated that by optimizing the spoke thickness through regression model and multi-objective genetic algorithm，the mechanical performance of the non-pneumatic tire with honeycomb structure was closer to that of pneumatic tire.Without changing the quality of the wheel spokes，compared with the non-pneumatic tire with honeycomb structure and uniform spoke thickness，optimized non-pneumatic tire with honeycomb structure and spoke thickness gradient variation had significantly reduced stiffness and improved stability during rolling.
