Simulation Analysis of Wheeled Vehicle Skid-Steer
In this paper, the wheeled vehicle is regard as a multi-rigid-body system and simulation model of the vehicle is established firstly by using dynamics simulation software of mechanical system ADAMS which is used most widely in the world. Secondly, through setting the initial condition and inputting various parameters, simulation analysis of skid-steer during the unilateral braking process and swerving braking process that the vehicle runs roundly in constant speed of 10km/h and 20km/h respectively is performed. In addition, vehicle velocity curves are recorded, vehicle yaw angular velocity curve are showed, Side accelerated speed curve is seen, the turning track curve of centre is drawn and the results are contrasted. Finally, some conclusions are reached that the vehicle minimum turning track radius decrease immensely than the radius which does not adopt unilateral braking and vehicle velocity could be controlled in a small velocity rage when vehicle is steering braking.
