Abstract
An apparatus and method are disclosed for modeling at least a portion of a rolling tire (). A finite element model of at least a portion of a tire () rolling against a tire contacting surface () is input into a finite element analysis system (). The system executed instructions that result in the application of a constant force to the model tire () or portion thereof by the tire contacting surface (). The application of force control boundary conditions, as opposed to displacement control, provides significant benefit in terms of computational time of the finite element analysis solution. A finite element analysis simulation of the model against the tire contacting surface () is performed while maintaining the force on the model tire (). Alternatively, a camber (γ) is also applied to the tire and maintained throughout the simulation.
