Magic Formula Tyre Model with Transient Properties
TLDR
In this article, the steady-state empirical "Magic Formula" tire model was used to model the acceleration and braking properties of the Delft Tyre 97, and a full set of equations of the steady state part of the model of the new version was presented.Abstract:
The tyre force and moment generating properties connected with the vehicle's horizontal motions are considered. Knowledge of tyre properties is necessary to properly design vehicle components and advanced control systems. For this purpose, mathematical models of the tyre are being used in vehicle simulation models. The steady-state empirical ‘Magic Formula tyre model’ is discussed. The aligning torque description is based on the concepts of pneumatic trail and residual torque. This facilitates its combined slip description. Following Michelin, weighting functions have been introduced to model the combined slip force generation. A full set of equations of the steady-state part of the model of the new version ‘Delft Tyre 97’ is presented. The non-steady state behaviour of the tyre is of importance in rapid transient maneuvres, when cornering on uneven roads and for the analysis of oscillatory braking and steering properties. A relatively simple model for longitudinal and lateral transient responses...read more

The In-Plane Dynamics of Tyres on Uneven Roads
Peter Zegelaar,Hans B. Pacejka +1 more
TL;DR: In this article, two situations of the tyre rolling over unevennesses are analysed using experiments and simulations: quasi-static rolling at very low velocity and dynamic rolling at high velocity. But the results of these experiments were not used to simulate the dynamic behaviour of the tire rolling over the unevennesses, also at higher velocity.
The tyre as a vehicle component
TL;DR: In this article, a simple brush tire model is treated first to gain insight and then, the steady-state empirical "Magic Formula tyre model" is discussed, and a description of the steady state part of new version 'Delft Tyre 96' is added.
