Dividing the assembly body of behavior simulation method of the assembly body of the tire and the wheel and

摘要

PPROBLEM TO BE SOLVED: To accurately simulate the behavior of a tire, in the analysis of the tire by a numerical analysis method such as the finite element method (FEM). PSOLUTION: In order to analyze the behavior of the tire in simulation, when the tire is calculated by applying it to a numerical calculation model, an analysis condition is input, a tire model is produced, an assembly model is produced, a road surface model is produced, a boundary condition is produced, deforming calculation of the assembly model is executed, and a result thereof is analyzed (steps 100 to 114). At that time, in order to decide a rotating position, the displacement of a point capable of rigidly indicating the rotation displacement of the tire or the wheel is made to be the reference point displacement. By analyzing physical amount with the reference point, and calculating a difference between a uniform tire and a nonuniform tire, different speeds or loads, and different inner pressures to assure accuracy.
