摘要: Abstract The finite element method [FEM] of analysis previously developed for prediction rigid wheel-soil interaction is improved and extended to take into account (a) the effect flexibility tyre carcass where energy losses now occur in development mobility, (b) a simpler requirement specification boundary condition using input loading, (c) normal tangential load stress from distributed across tyre-soil interface varying with slip. comparisons analytically computed (predicted) drawbar pull actual experimentally obtained results tests three types tyres show good correlations. inflation pressure on deformation can be seen values.
