Geometric analysis of maneuverability performance for vehicles with two steering axles

Abstract

One of the most important features of motor vehicles is their steering maneuverability. Ways of determining single axle steering are well known. This paper presents an idea of how to determine maneuverability of motor vehicles with two steering axles. The concept makes use of elements of kinematic analysis as well as of a 3D model of the steering system. It is based on the theoretical analysis of the most unfavorable situations, such as parallel and perpendicular parking techniques, on the basis of which wheel-steering angles are specified. As a result, it was possible to create a 3D model to simulate the actual operation of the steering system. This made it possible to compare the theoretical approach with the actual system design.
