Analysis of tire forces in cornering situations using python modelling

Abstract:
Nowadays, the automobile industry is developing rapidly, which has led to much research on these aspects, such as force analysis on the tires when the car is in different conditions, the degree of damage under different impacts. Hence, this article is focused on analyzing the force on the tires when the car is in lane change and in U-turn. In order to make the process efficiently and clearly, we use python language to establish an appropriate model. This method might help to judge the force's inclination and other essential factors. These factors might influence the force in these two moving statuses. The data is based on two typical model: BMWM3 and Chevrolet Cavaliers. As a result, some important, eternal parameters about these two models are referred directly from the official website. Some examples are the length of the car and the location of the centroid and etc. As a result, the ultimate images which show the variation of force with slip angle can be presented. Through the images, it could be indicated that in the Nonlinear type, the magnitude of the force will remain unchanged no matter in the front tire or rear tire. Besides, the relationship between the way of change and the slip angle could also be reached simultaneously. Based on this, it will find the final conclusion about the force in different conditions with different tires.
