Graphical Methods for Road Vehicle System Dynamics Analysis

Paper i proceeding, 2022

This methods paper is an attempt to place a few of the classical vehicle dynamics analysis methods in a common framework and how the methods can be used in combination to analyze different aspects of the planar motion of road vehicles. The methods described are the handling diagram for analysis of the non-linear steady-state characteristics, the phase plane analysis method to analyse the dynamic characteristics of a particular fixed point (or several) and the Milliken moment method diagram. In summary these methods are used to analyse the planar motion of the vehicle. The purpose of this methods paper is to present each method in detail and how they can be computed using a common vehicle dynamics model. Furthermore, the relationship between different points in the different representations are presented.
