| 摘 要： | 以地铁车辆限界标准为基础，以某地铁工程车为例，对例举的3种非正常工况下的车辆动态包络线进行计算，并对结果采用图形对比的方式进行了比较，通过对比分析认为在非正常工况下需要更大的车辆限界。为车辆在运行过程中，出现非正常工况时，车辆是否会超限提供理论依据，也为今后对非正常工况下的车辆限界计算提供一种参考，保障车辆运行安全。

| Abstract: | The dynamic envelope of vehicles is calculated under three abnormal conditions based on metro vehicle gauge, considering a rail flaw detection car as an example. Results are compared graphically. According to the comparison and analysis, it is considered that larger vehicle gauge is required under abnormal conditions. A theoretical basis is provided for whether a vehicle will be out of gauge during abnormal operation. In addition, this study provides reference for the calculation of vehicle gauge under abnormal conditions for ensuring the safety of vehicle operation. |
