摘　　要：为实现安全运行,现代有轨电车在自动控制或人工控制运行方式下,均需要通过计算列车的安全制动距离来控制其运行速度。参考国际标准规定的CBTC系统超速防护安全制动模型,提出了该模型下列车安全制动距离的计算方法。利用该方法,计算了现代有轨电车在直线路段不同坡度、不同制动率条件下的安全制动距离和制动时间。通过对制动距离变化规律的分析并结合有轨电车线路条件,对现代有轨电车自动控制和人工控制2种运行方式提出了建议。通过对制动时间变化规律的分析,得出现代有轨电车制动时间与制动初速度呈明显线性关系,并对其产生原因进行了分析。In order to achieve safe operation,modern trams need to control their running speed through calculation of the safe braking distance under the automatic control or manual control operation mode.Referring to the safety braking model of the CBTC system for overspeed protection stipulated in an international standard,a calculation method for train safe braking distance is proposed.The method was used to calculate the safe braking distance and braking time of modern trams under different gradients and braking rates in the straight line section.Based on the analysis of the variation regularity of braking distance and combined with tram line conditions,some suggestions put forward are put forward for the automatic control and manual control of modern tram in this paper.By analyzing the variation regularity of braking time,it is concluded that there is a clear linear relationship between braking time of tram and its initial braking speed,the reasons for its occurrence were analyzed.
