  • The aluminum extruded sections are used to the light construction of the high speed rail vehicle structures. However, the research works on the crashworthy design of aluminum extruded sections are not published sufficiently. In this paper, the collapse characteristics of aluminum extruded sections are investigated by crush test and simulation. The scale model studies are also performed to predict the impact energy absorption characteristics of full scale model through axial crush test and simulation.

  • The substructure of Light Rail Transit is mainly built on elevated structure that is composed of pier, girder and bridge deck. The bridge deck mostly has been made by field formed reinforced concrete so far. The objectives of the study are to find a method for design and construction of the new bridge deck. I-beam is fabricated to make grid and concrete is poured on it at factory. This type can be used for maintenance of duty line by advantages such as good quality control and short construction time.

  • Nowadays, Short headway is a requirement of Signaling System applied to subway and Light Rail Transit (LRT) being constructed in Korea. To satisfy this Systematic Requirement, the accuracy of train position information on the line is one of the main element to improve ATC system safety and performance. On-board ATC system performs feasibility of Train Position as comparing data from balise installed along the track with data from tachometer installed at both axles of train.

  • In this study, the carbody design of the rubber tired AGT(Automated Guide-way Transit System) under development by KRRI was numerically analysed to evaluate its structural strength according to the standard specifications for Korean LRT (Light Rail Transit). The numerical results showed that the detail design of the carbody was strong enough to satisfy the specifications with respect to the axial compression strength, the vertical strength and the vertical stiffness(natural frequency). However, the carbody design had some problems on the fatigue strength by twist loadings. So, it was recommended that the carbody design should be modified to improve the twisting strength by reinforcing the front end structures.

  • The interests of the government and civil business owner against the Light rail transit are increasing, it may be caused by the enterprise conception which does not consider a city circumstance that the construction plan is insensitively performed. This article present the forecast method of minimum transportation demand which secures a profitability. If It is in advance investigated the number of passenger using the existing traffic system of the area, it will be possible that the LRT project is planned on a realistic basis.

  • 우리사회는 교통시설부족으로 인하여 많은 사회적 비용을 지불하고 있다. 이에 따라 꾸준한 지하철, 도로등 교통시설을 확대하고 있으나 지하철과 도로망 확대 모두 재원 문제로 많은 어려움을 겪고 있다. 따라서 지하철보다는 수송용량은 떨어지나 건설비 및 운영비를 절감 할 수 있고, 도로건설에 따른 도시에서의 용지 확보문제를 동시해결 할 수 있는 경량전철이 계속 심도있게 부각되고 있다. 본 글은 우리 철도학회 회원들에게 경량전철의 개황과 현재 운영 또는 개발되어 있는 각종 시스템을 소개함으로서 경량전철을 이해하는데 도움을 주고자하여 이글을 기고합니다.

  • The LIM can be used as a transport system with wheel structure. The structural tolerance cause the airgap unbalance and that effects on the LIM performance. The effect of airgap unbalance on the motor performance such as thrust force, velocity and armature current are investigated by using Finite Element Analysis (FEA). From this numerical works, it is known that the airgap unbalance almost does not effect on the motor performance and LIM for transport system is robust to the structural tolerance.
