南宁地铁1号线列车自动运行模式下列车停车精度优化设计

Optimized Design of the Stopping Precision in ATO Mode on Nanning Metro Line 1

以南宁地铁1号线ATO(列车自动运行)模式下列车停车精度为研究对象,以停车精度的统计数据为依据,通过对ATO制动力和电空制动配合两个方面进行分析,找出了停车精度不准的根本原因。进行了ATO模式停车精度的优化设计,并在实际运营线路上进行了测试验证。测试结果表明,南宁地铁1号线ATO模式下列车停车精度的优化设计方案可行,列车停车精度得到了较大的提高。

Focusing on the stopping precision in ATO mode on Nanning metro Line l, the statistical data are used to analyze the ATO brake force, the coordination of electrical dynamic and pneumatic braking, and the main reasons for the inaccurate stopping precision are detected. Then, an optimal design for stopping precision in ATO mode is con- ducted, which is verified on the actual operating lines. The test results show that the optimal design for stopping preci- sion in ATO mode on Nanning metro Line 1 is feasible, and the stopping precision has been greatly improved.
