Abstract
The common feature of forced and self-excited vibrations encountered in motor vehicle front wheels lies in the fact that a certain amount of energy is fed back via tire-road interaction from the engine to front axle steering system, which may result in the presence of negative damping as in self-excited vibration.
This paper presents two mathematical models for vibration analysis namly, an eighth order mathematical model of the front-axle steering system and a composite mathematical model comprising both front-axle steering system and the whole suspended structure with it's own modal parameters. The theory and method presented in this paper are in accord with actual tests on certain vehicles.
