摘　　要：基于降低货车内轮差安全隐患的考虑,根据已有的研究成果对半挂车内轮差问题改善方向提出设想,基于刚体运动学原理提出具体改进方案,导出转弯时半挂车运动轨迹方程,运用Matlab软件从理论上进行了验证。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 speciˉc measure to derive the trajectory equation of semi-trailer movement during turning,and veriˉed it theoretically using Matlab.
