고무차륜형 AGT 경량전철 차량용 알루미늄 차체의 개발

Based on the design requirements(size, strength, structure, weight, and etc.) for the rubber-tired AGT vehicle, carbody made of aluminum alloy is designed. The analysis of strength and stiffness is performed in the designed carbody, which results in the modification for optimal shapes and structures. It consists of a under frame, side frame, roof frame, end frame and forehead frame. After the carbody manufactured, tests are performed, which are vertical load test, longitudinal compressive load test, 3 points supporting test. Results of them can guarantee a structural safety.
