Abstract: The evaluation of the vertical loads on kart tyres is examined in this paper. A detailed finite element model has been developed to perform static analysis, considering five conditions: longitudinal acceleration, lateral acceleration, vertical acceleration and two vertical displacements, that represent the lift of front wheels hubs caused by the steering kinematics. The solutions obtained have been combined to obtain the vertical loads values in generic driving situations. After the analysis of trimmed vehicle conditions, the evolution of vertical loads in a complete lap has been examined. Feeding the model with actual steering and acceleration data, it|s possible to highlight and optimise critical areas.
