With increasing international interest in further environmental problems and energy, prospects are that interest in railroad is increased emerging the importance of railroad which has high energy efficiency. In addition, a rate of sharing freight of railroad is expected to be increased gradually because existing line became under freight-based operation and investment in railroad was expanded since the completion of Kyoung-bu new line. Therefore, research of Korean DMT freight car is required in accordance with these increase in a rate of sharing freight of railroad.
In this paper, we have tested parts and systems necessary for the basic design and developed analysis model combined with those components in order to ensure running safety of Korean DMT freight car on existing line. Especially, we analyzed the running performance of the Korean DMT freight car passing through the curve by its vibration and transmission process. In results of the running performance analyzation at curve section, the right & left acceleration of the vibration which is delivered from wheelset to the carbody appeared most greatly at all positions & systems. And the vibration which is delivered to wheelset→bogie→carbody is decreased gradually. Also the up & down vibration due to the decrease in transmission process appeared most greatly.
