直线电机轮轨交通车辆通常车厢底板高度低,车体尺寸小,与传统地铁车辆相比,具有车辆限界小的特点.目前地铁车站站台边缘与车体间空隙过大,导致乘客上下车时经常发生踏空受伤事件.本文针对广州地铁4号线直线电机轮轨交通系统,采用车线动力分析的方法,建立了直线电机轮轨车辆侧向动态偏移计算模型,在此基础上分析了不同线路状态、不同运行速度等条件下车辆各方向运动情况,计算了站台面高度处车体的横向最大侧移,并以该值作为车辆限界确定站台与车辆间空隙.研究表明:广州地铁4号线站台与车辆间隙还可以缩小20 mm.

The vehicle powered by linear induction motor (LIM) features the lower bottom of carriage and smaller gauge, compared with the traditional metro vehicle. The gap between the carriage and platform edge is comparatively large at present, which may cause accidents to passengers. In this paper, a computational model of the dynamic lateral motion of LIM vehicle is presented. Based on this model, the maximum value of the car body lateral shift at the position parallel with the altitude of platform is analyzed under various track condition and running speeds. Then the appropriate gap between the vehicle and platform are investigated. The results show the present gap applied in Guangzhou Line 4 can be reduced by 20 mm. the proposed method for computing vehicle gauge can accurately evaluate the dynamic lateral movement of the vehicle, which can provide a more reliable basis for selecting the reasonable gap between the vehicle and platform accordingly.
