摘　　要：本文针对半挂列车转弯产生的内轮差危险区域进行了研究,建立了半挂列车简化模型。通过该模型推导计算出稳态转弯工况内轮差公式,设计了可为行人展示的动态内轮差区域投影装置。装置安装在左右后视镜下方,依靠车轮转角控制舵机进行角度调整。实现了半挂列车内轮差的主动预警,直观的展示汽车转弯危险区域,强化装置对行人的警示作用。In this paper,the danger area of inner wheel difference caused by semi-trailer train turning is studied,and a simplified model of semi-trailer train is established.Based on the model,the formula of wheel difference in steady-state turning conditions is calculated,and a dynamic inner wheel differential area projection device for pedestrians is designed.The unit is mounted under the left and right mirrors and relies on the wheel corner control rudder for angle adjustment.The active warning of wheel difference in semi-trailer train is realized,the dangerous area of car turning is displayed intuitively,and the warning effect of the device on pedestrians is strengthened.
