Abstract: Based on the considerations of reducing the safety hazard of wheel difference in trucks, this paper proposes an improvement direction of the inner wheel difference problem of semi-trailer based on the existing research results. Based on the principle of rigid body kinematics, it proposes a specific measure to derive the trajectory equation of semi-trailer movement during turning, and verified it theoretically using Matlab.
