山西中南部铁路壶关至红旗渠段长大坡道缓坡设置研究
Research on Setting of Slight Gradient between Huguan and Hongqiqu on Central and Southern Shanxi Railway
摘要
Abstract
The Central and Southern Shanxi Railway is a new line for 10 000-ton trains, and the first domestic line on which trains of 30t axle load 10 000-ton are tested. The design of vertical section and stations distribution of this railway has to satisfy the cycle braking and longitudinal impulse of 10 000-ton trains. This paper uses train longitudinal dynamics simulation software to guide the design of heavy haul railway. With simulations of 10 000-ton trains hauled by different locomotives, limited braking speed, braking length, operation safety and longitudinal impulse are analyzed when 10 000-ton trains run on the long downhill slope. Slight gradient of the long downhill slope between Huguan and Hongqiqu is studied so as to meet the requirements of operation, maintenance and rescue under abnormal conditions. Research suggests that one slight gradient shall be added between Huguan and Hongqiqu and rescue equipment provided. The research results have been applied in project design, an additional station is provided between Huguan and Hongqiqu with locomotive waiting track and equipped with double machine reconnection rescue locomotive.关键词
