This example problem simulates radial tire operation under various operating conditions. Tire simulation using finite element analysis is an established and efficient method for determining and improving tire performance.
Tires are complex composite structures comprised of hyperelastic materials (such as rubber) and reinforced structural materials (such as steel cords, modeled as linear elastic materials).
The following features and capabilities are highlighted:
Axisymmetric element with torsion capability (PLANE182).
Modeling reinforcing elements via the mesh-independent method for defining reinforcing.
2D to 3D analysis to extrude a 2D axisymmetric tire model to a 3D model (EEXTRUDE), then map solution variables from the 2D mesh to the new 3D mesh and rebalance the results (MAP2DTO3D).
Continuing the analysis on the 3D model via a multiframe restart.
Steady-state rolling analysis (SSTATE) using Arbitrary Lagrangian-Eulearin (ALE) formulation.
