Method and system for predicting radial rigidity of tire and computer software

Abstract

The invention relates to the technical field of finite element simulation analysis of tires, in particular to a method and system for predicting radial rigidity of a tire and computer software. The method comprises the following steps: firstly, acquiring experimental data under different tire models and working conditions, and identifying key factors influencing the radial rigidity of the tire, such as air pressure, load, tire size and the like; and then, establishing a mathematical model by using a statistical analysis method, and fitting experimental data with the model so as to accurately predict the radial rigidity of the tire. The method not only simplifies the prediction process of the radial rigidity of the tire, but also greatly reduces the cost and time consumption. Compared with a traditional laboratory test and simulation analysis method, the method has the advantages of being easy and convenient to operate, free of high-skill operation, high in calculation speed and the like, an efficient and accurate prediction tool can be provided for tire designers, and improvement of performance optimization of tires and controllability and comfort of vehicles is facilitated.
