Abstract
A multi-body kinematic modeling method is proposed and simulated for the trajectory deflection of the rear axle of the trailer during the right turn of A-Double Vehicles. Firstly, based on the kinematic theory of the multi-body system, a kinematic model of the vehicle double-track is established and the overall equations of motion of the vehicle right turn are derived. Secondly, MATLAB software was used to calculate and simulate the trajectory of each wheel during the right turn of the vehicle. Finally, the influence of vehicle wheelbase and trailer wheelbase on the offset of trailer rear wheel trajectory was compared and analyzed. The results show that the appropriate reduction of the trailer wheelbase can effectively reduce the offset of the trajectory of the rear wheels of the trailer during the right turn of the A-Double Vehicles and improve the driving safety of the vehicle.
