重载列车分相区限速曲线优化方法
Optimization Method for Speed Limit Curve in Neutral Zone of Heavy-Haul Train
摘要
Abstract
In order to solve the technical issue of air braking triggered by overspeed at downhill slopes in the neutral zone during automatic train control of heavy-haul trains,this paper proposes an optimization method for the Automatic Train Operation(ATO)control curve for heavy-haul trains.Based on the decelerated operating characteristics of and the relevant neutral zone information for some heavy-haul trains that can only be controlled by air braking in the neutral zone,it provides an optimized design for the ATO speed limit curve.Experimental verification shows that the proposed method effectively avoids the application of air braking due to overspeed in the neutral zone,and solves the problem of train coupler squeezing in this scenario.Moreover,it avoids the problem of premature train stopping when the train speed is lower than the unreleasable speed through curve optimization.This research provides technical support for the stable and safe operation of heavy-haul trains in the neutral zone.关键词
