Abstract
Easy-to-use tire models for vehicle dynamics analysis have been studied at various institutions. This paper presents a tire model consisting of theoretical and experimental equations representing the experimental characteristics of tires, by employing relatively simple theoretical equations (1), (2), (3) and (4)*, obtaining their coefficients through experiments, and adding further corrections.
As a result, we have obtained a model representing the change of forces and moment generating in the tire, which are caused by slip angle, slip ratio, camber angle and load.
This model has many advantages including easy correspondence to physical phenomena, higher possibilities of practical development and a possibility of rational correction of the errors during experiments.
