Abstract

This paper shows the theoretical analysis of the wandering phenomenon using characteristic equation of the vehicle body. At first the equations of the vehicle motions on the dented wheel tracks on damaged roads are introduced and linearized to get a Laplace-transformed characteristic equation, considering the interaction between the inherent vehicle dynamics and the dented track profiles. By this fourth order equation, the vehicle body fluctuations on the dented tracks are theoretically discussed and verified by computer simulation. It is found that the vehicle body fluctuations on dented tracks are much influenced by forward velocity, wheel track depth, and vehicle parameters.
