Theoretical and Numerical Analysis on the Static-Loaded Contact Pressure of Mechanical Elastic Wheel
This paper describes the theoretical and numerical methods to calculate the contact pressure of Mechanical Elastic Wheel (MEW). The structure of MEW was introduced firstly, and then the contact pressure of MEW was calculated with the simplified model of a single layer composite ring according to Elasticity. Considering the structure and force symmetry, 1/2 finite element model of MEW was built. Mooney-Rivilin hyperelastic constitutive model was applied to simulate material nonlinearity, and frictionless contact type was applied to simulate nonlinear contact characteristics. With the Augmented Lagrangian solving method, the contact pressure analysis result of MEW was obtained. The theoretical and simulation values of MEW’s contact pressure are approximate with the deviation of 1.08%, and it indicates the validity of the simulation.
