Recently, with the development of railage, passenger transport, freight and the density of train have increased mostly. it results in rail - wear day after day, especially the side rail - wear. so the ministry of railway has been taking the situation of rail into account greatly to insure train and rail safely
近年來隨著鐵路重載運輸的大力發展,客貨運量和行車密度大幅度增長,從而導致鋼軌磨耗日益嚴重,尤其是曲線鋼軌的側面磨耗急劇上升,因此鐵路工務部門十分重視對鋼軌傷損情況的檢測,以確保行車的平穩性和安全性。Based on the data of curve track abrasion measured in beijing metro, the types of track abrasion of metro are analyzed, and the main reasons of track abrasion, and the basic methods to reduce the track abrasion and their application in beijing metro are presented
摘要準確簡要地描述北京地鐵彎道線路上鋼軌側磨的病害情況,根據現場測量數據統計側磨的類型、分析磨耗的主要原因、提出減緩磨耗的措施,並介紹現場的實際應用效果。Side wear of rail on curves is a normal phenomenon in railway engineering. a great quantity of rail wear results in decreasing rail life in use and increasing railway transportation costs
鋼軌側面磨耗是工務工程中普遍存在的問題,大量的鋼軌磨耗縮短了鋼軌的使用壽命,增加了鐵路運營成本。Considering the two advantageous enterprises - dalian port and dalian bonded zone, mainly dalian port, as the base of dalian international logistics park, the paper focuses on the analysis of outer supply, regional economy, demands of park and orientation model of park. otherwise, it makes the plan of market orientation of park and sets the model of business and then designs the functions of park. on these grounds, the transport infrastructure in the park is designed with the accent on the details of roads e. g
本文從大連國際物流園區發展的立足點- - - -大連港和大連保稅區兩大優勢實體出發,側重於大連港,通過對大連國際物流園區的背景分析、區位經濟分析、園區需求分析、園區定位模式分析及物流園區的定位、定性、定量、定序的研究,規劃出大連國際物流園區的市場定位,確定其核心業務模式,設計其主要功能,並以此為前提,進行園區集疏運系統的設計,園區水路、鐵路主要依託大窯灣港區的集疏運系統,園區內部路網是設計的重點,側重於細節設計,如紅線寬度、斷面結構等。With the increase of the electric power system capacity as well as the short lines, high currents will possibly occur in the transmission line when a fault happens at the end of the line. the iron core of the current transformer ( ct ) will become saturated easily because of the large current, or when the secondary load of the ct does n ' t match the 10 % error curve
隨著電力系統容量增大以及短線的增加,在電力系統線路末端發生短路時,有可能出現很大的短路電流;在很大短路電流的作用下,或由於電流互感器二次側負載與10誤差曲線不匹配等原因,電流互感器鐵芯很容易飽和。分享友人
