TLDR
The Magic Formula model as mentioned in this paper provides a set of mathematical formulae from which the forces and moment acting from road to tyre can be calculated at longitudinal, lateral and camber slip conditions, which may occur simultaneously.Abstract:
An account is given of the latest version 3 of the Magic Formula tyre model. The model provides a set of mathematical formulae from which the forces and moment acting from road to tyre can be calculated at longitudinal, lateral and camber slip conditions, which may occur simultaneously. The model aims at an accurate description of measured steady-state tyre behaviour. The coefficients of the basic formula represent typifying quantities of the tyre characteristic. By selecting proper values, the characteristics for either side force, aligning torque or fore and aft force can be obtained. The new version of the model contains physically based formulations to avoid the introduction of correction factors. Double-sided, possibly non-symmetric pure slip curves are employed as the basis for combined slip calculations. Suggestions are given to estimate the driving part of the longitudinal slip curve and to represent the characteristic at rolling backwards.read more

Pitch plane analysis of a twin-gas-chamber strut suspension
TL;DR: In this article, a twin-gas-chamber hydropneumatic suspension strut concept is proposed to achieve enhanced bounce and pitch ride, and pitch attitude control in a pitch plane vehicle model, subject to straightline braking inputs and excitations arising from randomly distributed road elevations.

Static stiffness characteristics of a new non-pneumatic tire with different hinge structure and distribution
TL;DR: Based on the analysis of the bearing characteristics, four types of ME-wheel with varying hinge structures and distributions were designed and the static stiffness characteristics of these four ME-wheels were investigated by numerical simulations and experiments as mentioned in this paper.

An Analytical Tire Model with Flexible Carcass for Combined Slips
TL;DR: In this article, an analytical tire model with flexible carcass for combined slip situations was presented, which can describe tire behavior well and can also be used for studying vehicle dynamics, where the tire forces and moments come mainly from the shear stress and sliding friction at the tread-road interface.

TL;DR: In this article, a detailed overall ORC simulation model is presented based on two solution strategies: condenser subcooling and total working fluid charge of the system, which allows the sub-cooling level to be predicted rather than specified as an input.

TL;DR: In this article, the Magic Formula Tyre Model is compared with the Monte Carlo version of the model and the comparison between the two versions shows that the latest version results in better fitting results especially for camber influences and (even more important) in an improvement on the fitting process.
