Transient and steady-state rotation center of vehicle dynamics

Abstract

The purpose of this paper is to show the effect of acceleration-variable forward \nvelocity-, on the steady-state and transient responses of turning vehicles and the resulted \npath of motion of the vehicle. Comparing the responses of the vehicle will be used to prove \nthat there is a negligible difference between the steady-state and transient center of rotation \nof the vehicle in engineering applications. To show that vehicles are working close to their \nsteady-state conditions even at transient stage, we examine a vehicle in two maneuvers. In \nthe first one, the vehicle is assumed to be moving at a constant forward speed and \nexperiencing a step steer angle change. In the second maneuver, the vehicle experiences a \nlane change steering input. The transient response of the vehicle, as well as the required \ntime to achieve the steady-state conditions will be analyzed.
