| Abstract: | In this paper,mechanism dynamics simulation technology has been used to analyze the characteristics of transient and steady dynamic responses of 4WS vehicle. A multi-body dynamic model for a 4WS vehicle is set up using ADAMS software base on virtual prototyping technology and a simulation is carried out at different rotation angles, rotation directions of front and rear wheels as well as different time differences of rotation between front and rear wheels. The results are analyzed and some conclusions on the transient and steady maneuverability of the vehicle are drawn. |
