【摘要】：随着经济的迅猛发展,人民生活的不断提高,对铁路运输的需求不断增大,为适应国民经济发展和市场经济的需要,铁道部提出了跨越式的发展战略,在既有线路上大范围进行扩能及提速改造并修建客运专线铁路,并改善现有的行车组织模式,提高装备水平,进而影响到旅客列车年货运量折算值。在此背景下,本文对旅客列车年货运量的折算值进行研究,为线规的修编提供参考。本文主要通过对旅客列车的扣除系数及货物列车的牵引质量两个影响因素进行分析,进而计算旅客列车年货运量折算值。首先,通过对货物列车牵引质量的分析与研究,得到了在不同限坡条件下不同类型的货物列车的牵引质量。通过对“和谐”型货运机车的实际牵引质量与理论牵引质量的对比,提出了用计算粘着牵引力计算牵引质量的方法。其次,通过对影响旅客列车扣除系数的主要因素进行分析研究,运用图解法,得出了不同行车组织模式下旅客列车扣除系数的计算方法及其取值,并提出旅客列车扣除系数的变化规律,为行车组织的合理安排提供了一定的理论依据。最后,应用MATLAB软件中的randsample函数对货物列车牵引净载及旅客列车扣除系数的数据进行处理,进而得到旅客列车年货量折算值,并建议纳规值为1.5Mt,可为铁路等级的划分和正线数目的确定提供了定量的参考依据。综上所述,本文通过对货物列车牵引质量的分析与研究,得到了在不同限坡条件下不同类型的货物列车的牵引质量,分析了总结了不同行车组织模式下旅客列车扣除系数的计算方法,并通过应用randsample函数计算一列旅客列车年货量的折算值。
[Abstract]:With the rapid development of economy, the continuous improvement of people's life and the increasing demand for railway transportation, the Ministry of Railways has put forward a leapfrog development strategy to meet the needs of the development of national economy and market economy. On the existing lines, the capacity expansion and speed increase are carried out on a large scale and the passenger dedicated railway is built, and the existing train organization mode is improved, the equipment level is raised, and the value of the annual freight volume of passenger trains is affected. Under this background, this paper studies the commutation value of annual freight volume of passenger train, and provides reference for the revision of line rules. Based on the analysis of two factors, the deduction coefficient of passenger train and the traction quality of freight train, this paper calculates the value of the annual freight volume of passenger train. Firstly, through the analysis and research on the quality of freight train traction, the traction quality of different types of freight train is obtained under different slope limiting conditions. Based on the comparison between the actual traction quality and the theoretical traction quality of the "harmonious" freight locomotive, the method of calculating the traction mass by using the adhesive traction force is put forward. Secondly, through the analysis and study of the main factors affecting the passenger train deduction coefficient, the calculation method and the value of the passenger train deduction coefficient under different train organization modes are obtained by using the graphic method. The change rule of passenger train deduction coefficient is put forward, which provides a certain theoretical basis for rational arrangement of train running organization. Finally, the randsample function in MATLAB software is used to deal with the data of the net load of freight train traction and the deduction coefficient of passenger train, and then the value of the annual volume of passenger train is obtained. It is suggested that the gauge value is 1.5 Mt, which can provide a quantitative reference for the classification of railway grades and the determination of the number of main lines. To sum up, through the analysis and research on the quality of freight train traction, this paper obtains the traction quality of different types of freight train under different slope limiting conditions. This paper analyzes and summarizes the calculation method of passenger train deduction coefficient under different train organization modes, and calculates the annual volume of passenger train by using randsample function.
