도시형 자기부상열차 부상레일의 롤 성형공정 해석 = Analysis for Roll Forming Process to Levitation Rail of Urban Maglev System

다국어 초록 (Multilingual Abstract)

This Study discussed the roll forming process analysis of levitation rail for urban Maglev vehicle. To verify validity of roll forming process, we analyzed roll forming process for track shoe which is similar to levitation rail. The analysis process was composed of 12 passes and was performed for only 8 passes except overlapping passes.
In the variation of temperature with each pass, surface temperature of the structure was cooled from initial 1200℃ to 1010℃ during 30 second before first pass, and central temperature and surface temperature was cooled to 980℃ and 900℃ in final pass, respectively. A length of structure after final pass is about 5 times longer than that before roll forming process. A strain of structure had a higher value in the inner part of the track shoe and show from minimum 2.5 to maximum 6.5. A torque applying on roll appear high in 2, 3 and 4 passes and a maximum value was 27,000tonㆍ㎜. Also it was analyzed that a load to the normal direction needs maximum 300ton.
