论地铁车辆段试车线的功能及设计要求

Study of Metro Depot Train Test Line Function and Design Requirements

研究目的:地铁车辆段试车线是地铁列车进行动态调试和试验的线路,新车和检修后的列车都要在试车线上进行系统的调试及性能试验后才能上线运营。对试车线的长度、曲线半径、坡度等都有较高的要求。但试车线的布置又受用地条件的控制,因此在地铁车辆段设计中,合理确定试车线的功能需求,优化布置方案是需要重点解决的问题。研究结论:地铁车辆段试车线对保证列车运营的安全性和可靠性具有十分重要的作用,有条件时,试车线设计应尽可能满足最高运行速度的试车需求。当用地条件受控时,可针对不同性质的地铁车辆段按满足不同层次的试车要求确定车辆段试车线的设计方案,而必需的高速试车可在正线上实现。

Research purposes： The train test line in metro depot is used for train dynamic debugging and test. New trains and the repaired trains must be debugged and tested on the test line before service operation. The test line should be proper on the length, curve radius, grade, etc, but that is difficult to get, as the restricting of area. It should be emphasis that determine of function requirements and optimizing scheme of test line on the design of metro depot. Research conclusions：The test line in metro depot is necessary and important to ensure safety and reliability of train operation. The test line should be designed to meet the highest operation velocity test if site is available. When the site area is restricted, we should propose to determine the test line design standard according to the class of depot, and necessary high velocity test can be carried out on main line.
