Contribution to the investigation of the influence of tire non-uniformity on the lateral tire characteristics

Tire models are widely used in research the field of vehicle dynamics and noise, especially simulation their movement under action forces moments. In general case, we distinguish theoretical defined on basis tire construction empirical or semi-empirical based experimental tests. addition, a combination these two types can also produce models. practice, there is very wide range mathematical using finite element analysis, by approximation polynomials different degrees, magic formula, etc. this paper, an attempt made to calculate non-stationary lateral characteristics tires stationary characteristics, two-parameter higher level polynomials. This define take into account non-uniformity. More specifically, approximated as function dynamic change slip angle, radial load due non-uniformity time.
