Abstract
This study uses finite element tire model to explore the influence of driving conditions and structural design parameters on rolling resistance. Based on the results, low rolling resistance tire designs are proposed. This study creates finite element model for the 3.50-10 electric motorcycle tire with the finite element software Abaqus. Viscoelasticity is added to the finite element model. Elasticity and viscoelasticity are taken into account simultaneously during simulation of steady state rolling. Rolling resistance can be calculated directly from the analysis results. Besides, this study also calculates rolling resistance by the traditional method which separates the rubber elasticity and viscoelasticity. Experiments are used to verify the accuracy of the model and compare the above methods, which clearly show that the present method is superior to the traditional approach. Then the tire model is used to explore the influence of driving conditions and structural design parameters on rolling resistance, such as load, inflation pressure, driving velocity, camber angle, ply design parameters, tread pattern, etc. Finally, from analysis results, this study proposes new designs for a low rolling resistance tire by changing parameter, included ply angle, tread geometry and steel belts.
