摘要:
［目的］目前轨道交通全自动运行系统中各子系统设计方案的完备性，以及各子系统间的兼容适应度缺乏科学的评估方法，因此亟须建立1套轨道交通仿真测试平台进行验证评估。［方法］通过轨道交通仿真测试平台，基于线路和站场、信号系统及车辆系统等方面提出全自动运行系统的测试方法，进而评估相应系统的设计性能是否满足运营要求。以合肥轨道交通7号线为例，运用全自动运行系统测试方法对该线路的车辆系统、线路及站场及信号系统等的设计性能进行仿真测试验证。［结果及结论］在列车仿真测试运行过程中，线路最小曲线半径、线路坡度、站台长度、线路限制速度等线路和站场的设计指标，列车运行速度、技术速度、旅行速度、正线追踪间隔、列车停站时间等信号系统的设计指标，列车最大/平均启动加速度、列车常用/紧急制动减速度等车辆系统的设计指标均在可接受范围内，验证了全自动运行系统测试方法的可靠性。
Abstracts:
［Objective］ In light of the current lack of systematic and scientific evaluation methods for the completeness of subsystem design schemes, and the compatibility/adaptability among subsystems in rail transit FAO (fully automated operation) systems, it is urgently necessary to establish a rail transit simulation testing platform for validation and assessment. ［Method］ Based on the above testing platform, testing methods are proposed for FAO systems from the perspectives of track and station layouts, signaling and vehicle systems, in order to evaluate whether the design performance of the corresponding systems meets operational requirements. Taking Hefei Rail Transit Line 7 as a case study, the FAO system testing methods are applied to simulate and verify the design performance of the line vehicle system, track alignment and station layout, and signaling system. ［Result & Conclusion］ During the train simulation test operation, design indicators for tracks and stations such as track minimum curve radius, track gradient, station platform length, line speed limits; signaling system design indicators such as train operating speed, technical speed, travel speed, mainline tracking interval and train dwell time; vehicle system design indicators such as train maximum/average acceleration during startup, train service/emergency braking deceleration are all within acceptable range. The reliability of FAO system testing methods is verified.
