轮胎侧偏特性的半经验模型

The Semi-Empirical Model for Tire Lateral Properties

本文首先叙述了以前的理论模型(Fiala公式)和半经验模型(如桥石公式)的不足处。它们不能适用于接近极限工况而且试验结果与桥石公式差别不小。作者以Fiala公式为基础提出一个新公式,其中一些系数通过与试验数据拟合求得。 作者还用同样方法提出了回正力矩的新半经验模型。

First some old models are described, such as the Fiala model and Bridgestone formula, and their shortcomings are pointed out, mainly not suitable in extreme conditions, such as the vertical load of inner tire approaches zero.Then a new semi-empirical model based on the Fiaia model is given, with several coefficients determined by cut and trial to fit the experimental results.Also a new semi-empirical model for tire alignment torque is also given using the same method.
