  • The influences of high speed train on the dynamic responses of steel composite railway bridges are investigated. The bridge system which has two I-girder and several cross beams is modeled with plate and frame elements. With assumption of concrete slabs are fully connected with steel girders, the offset between slabs and girders is modeled using constraint equation. The track system is modeled using beams on elastic foundation theory. And, the TGV train model is developed in 2-dimension considering bouncing and pitching motion. And braking action of vehicle is considered using speed dependent braking function. To investigate the behavior of bridges due to moving trains, parametric studies on the variation of natural frequency of bridge, speed parameter, vehicle modeling method, braking action of train, etc are performed.

  • A dynamic analysis procedure is developed to provide a better estimation of the dynamic responses of pre-stressed concrete (PSC) box girder bridges on the Korea high speed railway. Particularly, a three dimensional numerical model including the structural interaction between high speed vehicles, bridges and railway endures to analyze accurately and evaluate with in-depth parametric studies for dynamic responses of bridge due to the high speed railway vehicles. Three dimensional frame element is used to model the PSC box girder bridges, simply supported span lengths 40 m. The high-speed railway vehicles (K-TGV) including a locomotive are used as 38-degree of freedom system. Three displacements (vertical, lateral, and longitudinal) as well as three rotational components (pitching, rolling, and yawing) are considered in the 38-degree of freedom model. The dynamic analysis by Runge-Kutta method which are able to analyze considering the dynamic impact factors are compared and contrasted. It is proposed as an empirical formula that the impact factors damaged the bridge load-carrying capacities occurs to the bride due to high-speed vehicle.

  • It has been 5 years since KTX high speed train was operated by KORAIL in Korea in April 2004. As for KTX train, France TGV was optimally renovated to make it, considering Korean geographical and environmental features. The research and development about KTX make it possible that train's exterior device design has the original design capability but, KTX train control & diagnosis design remains in the level of imitation. In order to analyze KTX train's diagnosis & control data, there are a collection method, using VME analysis device and method of analyzing control data structure and the operating and design capability about train control & diagnosis device should be secured. As the various high speed trains are operated in tracks, high speed train's safety driving and reduction of expense are necessary, by preparing in advance various train diagnosis & control which is indispensable to train operator. With the simplified train diagnosis & control design, Korean type high speed train's manufacture capability and operating capability should be improved and Korea's international status as a nation of operating high speed train should be established.

  • Using network communication, KTX OBCS is KTX's core device which inspects operation status of various electric equipments and supports driving command, train control, train's maintenance, train crew's driving. Since this device is manufactured as specialized system, being dependent on TGV manufacture specification and France's high speed train operation method, actual technic transfer is difficult. Therefore, there are many difficulties, since most of interface signals are connected with OBCS when function improvement, maintenance, various electric equipments(propulsion control device, auxiliary power supply device, door control device etc.) are replaced with localized ones, which are required in operational view after introduction of KTX. Ergo, this study would like to contribute to function improvement and maintenance's efficiency, furthermore to realize technical independence, escaping from dependency of developed foreign technology in high speed train and electric equipments, through KTX OBCS' function analysis and mutual interface information analysis with peripheral device(driver console, PID system, fault display device, various electric equipments).

  • The purpose of this study is to compensate for susceptibility and a ferromagnetic body artifact using CFA and TGV on MR Imaging. A total of 30 patients (15 men and 15 women, mean age: 45 years) were performed on head and neck diseases. MR Unit used a 1.5T superconducting magnet (GE medical system, High Density). This study have investigated by changing with CFA and TGV (70, 90, 110, 130, 150) searching for compensation values about susceptibility and a ferromagnetic body artifact in 60 kg standards of body weight (p<0.05). As a quality results, Image qualities were obtained at different score from CFA and TGV (70, 90, 110, 130, $150=3.23{\pm}0.35$, $4.31{\pm}0.02$ $4.23{\pm}0.21$, $5.12{\pm}0.25$, $7.13{\pm}0.72$, $8.31{\pm}0.01$, $5.21{\pm}0.15$, $6.14{\pm}0.08$, $5.23{\pm}0.72$, $5.91{\pm}0.06$, p<0.05). Absolute CNRs (TG, CNRpre, CNRpost) were acquired with (70:$-1.44{\pm}0.11$, $-2.7{\pm}0.04$, 90:$-2.18{\pm}0.42$, $-4.41{\pm}0.43$, 110:$-2.89{\pm}0.43$, $-5.23{\pm}0.02$, 130:$-2.34{\pm}0.05$, $-5.26{\pm}0.01$, 150: $-2.09{\pm}0.08$, $-3.87{\pm}0.12$, p<0.05).

  • Korea selected to introduce high-speed railway system from advanced countries in order to accumulate railway technologies and develop exiting domestic logistics system. After many twists and turns, we adopted to introduce France's high-speed railway called 'TGV'. Despite many difficulties along with trials and errors, it is expected that Korean high-speed railway will be brilliantly launched in April 2004, although it has been commissioned for multi-discipline tests. It is forecast that the opening of high-speed railway will bring us the epoch-making development of logistics system. However, what if there are really some problems in the operation of high-speed railway? We cannot consider and highlight only the positive aspects of our own high-speed railway. In terms of many challenging aspects we would face in the future, there would be some matters we must consider and point out in this opportunity. In this regard, the direction for developing high-speed railway stations requires the harmony between profitability and public benefits, which must involve compatibility with other traffice systems and practical policies to secure competitive edges.
