Adaptability Study Of Maglev Vehicle Bogie Frame At 600 Km/H

The 600 km/h high-speed magnetic levitation technology designed and developed in China lacks the test data at the speed of 600 km/h and the corresponding structural design specifications for high-speed magnetic levitation vehicles. In order to design a safe, reliable, and applicable vehicle structure scheme with high efficiency, the adaptability of key structures of existing highspeed maglev vehicle at the speed of 600 km/h needs to be studied. In order to studying the structural strength of the bogie frame used in Shanghai Maglev Line, a fine finite element model of the bogie frame was first established. The main loads used for studying the structural strength of the bogie structure were then obtained from the high-speed maglev vehicle dynamics simulation platform. According to the service environment, several typical load cases of the bogie frame were proposed. On this basis, the structural strength adaptability of the existing high-speed maglev vehicle bogie frame at the speed of 600 km/h was analyzed. The results show that the structural strength performance of the existing high-speed maglev bogie frame meets the requirements at the speed of 600 km/h. Furthermore, several design suggestions for corresponding component were proposed according to the structural strength analyze results. The methods adopted in this paper and the conclusions obtained in this paper have reference value for the design work of 600 km/h high-speed maglev vehicle in China.
