1 Challenge A:A more and more energy efficient railwayAstudy of the train performance simulation for Koreannext Generationhigh-speed trainTaehyung LEE, Choonsoo PARK,SunghoonCHOI,Kihwan KIMHigh-Speed RailResearch Center, KoreaRailroad Research Institute,Uiwang, KoreaAbstractThe next generation high-speed train system, HEMU-400X, has been developed in Korea since means High-speed electric Multiple Unit 300 experimental. Objectives of HEMU-400 Xproject is development of next generation high-speed electric multiple unit with maximum operationspeed 370km/h and maximum test speed 400km/h, energy efficiently and environment friendly. Atpresent, the detailed design and component manufacturing are in progress. Because of no experiencefor high-speedelectricmultiple units, the train performance simulation is used in the detailed simulation provides a valuable tool in the design of new high-speedtrain.

2 simulation systems arebeing used to validate the final designs prior to any manufacturing. The train performance simulationsoftware is developed during the previous project. This paper presents the procedure and method ofthe train performance simulation that have been carried out during the development of theHEMU-400X. For the train performance simulation , the train resistance model is suggested. Alsosuggested in this paper are the coefficients, such as the adhesion coefficient and the rotational simulations are studied for the performance satisfaction of HEMU-400X. It was found that thedetailed design specification of HEMU-400X satisfied the traction performance providesa valuable tool in the design of new rolling-stock.

3 simulation systems are beingused to validate the final designs prior to any manufacturing. In the design stage, the performancemodels of new rolling-stock are required. The performance models of new rolling-stock have the trainresistance model, the effective mass, the operation speed and the tractive effort-speed the model, the power and number of motor, time and distance to maximum speed, energyconsumption are determined. And using line profiles like gradients,curves and speed restrictions,running time and energy consumption next generation high-speed train system, HEMU-400X, has been developed in Korea since2007. HEMU-400X means High-speed electric Multiple Unit 400 experimental.

4 At present, the detailed designand component manufacturing are in progress. Because of noexperiencefor high-speed electric multiple units, the train performance simulation is used in thedetailed design. The train performance simulation software isdevelopedduring the previous , the length, dimensions, operation speeds and axle weights of HEMU-400X are definedbased on the domestic condition and abroad technology, such as the Shinkansen, ICE(Inter CityExpress) and TGV( train Grand Vitesse). HEMU-400X consists of 8 trains (6 motor cars and 2 trailercars) in case of revenue service. As a result, the running resistance model is defined based onJapanese Shinkansen train . From these parameters, the power and number of motor are , through train performance simulation , the maximum speed and time/distanceto maximumspeed is validated.

5 Also, the results of train performance simulation are used for establishing theminimum distance of test line. The characteristics of HEMU-400X are more energy efficient and moreenvironment friendly than the existing high-speed , when the detailed design is changed, mainly, train length, axle weight, tractive/brakingefforts and dimensions, train performance simulation is conducted modified design will provide the passenger service more energy efficiently and more environmentfriendly on the domestic and international high-speed A:A more and more energy efficient railwayAstudy of the train performance simulation for Koreannext Generationhigh-speed trainTaehyung LEE, Choonsoo PARK,SunghoonCHOI,Kihwan KIMHigh-Speed RailResearch Center, KoreaRailroad Research Institute,Uiwang, KoreaAbstractThe next generation high-speed train system, HEMU-400X, has been developed in Korea since means High-speed electric Multiple Unit 300 experimental.
