Development of New Articulated Structure and （开发新的和铰接结构）

Development of New Articulated Structure and Bogie for Korean High Speed Train (HSR-350X) 1H. Jung Presenting Author, 2W.S. Lee Coauthor, 3J.T. Kim Coauthor Hyundai Rotem Company., Uiwang, Korea1.2, LogoMotive Korea, Anyang, Korea3 Abstract A Korean High Speed Train(hereafter, HSR-350X), which is of an articulated train to be similar to TGV, has been developed and built by the Korean consortium since 1996. For improvement of HSR-350X, we have developed the horizontal articulated structure with new concept in comparison with the existing of vertical type. Due to the new articulated structure, automatically a bogie with four air spring system also has been developed newly to mount properly beneath the articulated structure. The articulated structure and bogie was designed through a dynamic and strength analysis. To prove the design, we have carried out many tests. Bogie frame has passed the fatigue test of the cycles of 10 millions according to UIC 515-4. And the articulated structure with rubber element has had the dynamic test of 4 millions cycles. After the test, no crack was appeared on the articulated structure. Lastly, during the running the HSR 350X on high speed line, safety and instability of new developed bogie was measured. It was assessed to be within the limits according to UIC 518. Introduction Since 1996, a Korean consortium composed of Hyundai Rotem Company and other Korean industrial companies, Research and development institutes and universities, has been developing a new articulated high speed train: the HSR-350X. During testing, in 2004, a HSR- 350X unit consisting of seven (7) cars has recorded a speed of over 352 km/h. Since then, the train has undergone a 200,000Km reliability test program. The new inter-car articulation of the HSR-350X is a novel design and maintenance friend
