3D-FE Simulations of Automobile Tires
This paper is concerned with finite element analyses of automobile tires, involving realistic numerical models for rubber and the reinforcing cords, frictional contact between the tire and the road surface and consideration of finite deformations. The long-term goal of these analyses is the optimization of the design of automobile tires on the basis of numerical simulations. Computational topics include a local mesh refinement technique developed for the coupling of a relatively coarse mesh for the tire with a considerably refined mesh for the contact zone of the tire and an efficient strategy for the iterative solution of the systems of equations. Selected results from large scale analyses of automobile tires involving 45,900 degrees of freedom are presented.
