Modeling Tractive Effort Torque of Wheel in Deformation Movements of Pneumatic Tire Wheel

The article is devoted to the simulation of torque moment through the deformation motion of the pneumatic wheel. Despite the fact that the dependence of torque moment of the vehicle from the slip value which can be interpreted as a vertical and angular deformation of pneumatic wheels, has been well studied, there are no adequate mathematical models. The article presents the results of a mathematical model and its numerical simulation which leads to the conclusion about the validity of the proposed approach for the description of the appearance of deformations in the pneumatic wheels and their connection with the vehicle driving torque. The mentioned three-dimensional interpretation of the simulation results is broadly consistent with the results of the experimental data.
