Abstract:  In order to further investigate lateral stiffness properties of mechanical elastic wheel, theoretical and numerical analysis on influencing factors was carried out. Theoretical model of lateral stiffness properties of tire bead unit was established based on energy method, and main factors influencing the wheel lateral stiffness were obtained. On the basis of simplified structure of mechanical elastic wheel, a threedimensional finite element model was established, and the corresponding simulation programs were designed for different vertical loads, structure parameters of tire bead and shear moduli of rubber layer. By using finite element analysis software Abaqus, numerical simulation calculation on lateral stiffness properties of mechanical elastic wheel was completed. And test data of prototype of mechanical elastic wheel were used to verify the validity of the wheel finite element model. The calculation results show that as vertical load or shear modulus of rubber layer increases, lateral stiffness of mechanical elastic wheel increases; with the increase of the depthwidth ratio of tire bead section, the wheel lateral stiffness shows a trend of decrease. Theoretical and numerical research on lateral stiffness of mechanical elastic wheel, reference was provided for optimizing wheel stiffness properties and improving wheel structure.
