双线自闭区段客货列车速度比对扣除系数的影响分析

The Affect Analysis about the Ratio of Speed to Deducted Coefficient in Double-line Block Sections

目前扣除系数的计算方法主要为分析法与模拟法,扣除系数的常见影响因素有客货列车速度比、区段均衡度、追踪间隔时分等。通过模拟法进行不同客货列车速度比下的运行图铺画,得出客货列车速度比对扣除系数的影响规律分析。实验表明:随着客货速度比的增加,扣除系数将逐渐变大,据此建议在相关双线客货混跑区段,选取合适的客货速度比,以减小对运行图通过能力的影响。

At present the removal coefficient calculation methods including analysis method and simulation method. Passenger and cargo train speed ratio, section balancing degree and headway constitute the common in- fluencing factors of removal coefficient. Using simulation method, this paper draws different train operation diagrams under different passenger and cargo speed ratios, and analyzes the law how passenger and cargo speed rati- o affect the removal coefficient. The experiment shows that with the increase of passenger and cargo speed ratio,removal coefficient keeps growing. According to this, it is recommended the related Double Track Railway with Automatic Block System elect the right passenger and cargo speed ratio to reduce the impact of the carrying capacity.
