ABSTRACT

The finite element model of the high-speed maglev track beam was established. The temperature field of the track beam was obtained by steady-state heat conduction analysis. The temperature deformation of the maglev track beam under different temperature loads was calculated by thermal-structural coupling analysis method. The calculation results show that the temperature gradient of maglev track beam increases with the increase of temperature difference. Moreover, the vertical or transverse deflection deformation of maglev track beam caused by temperature difference load increases with the increase of temperature difference. However, when the temperature difference load between upper and lower surfaces is greater than 20℃, the vertical deflection of maglev track beam caused by temperature difference exceeds the relevant stipulated limit of high-speed maglev traffic. Therefore, it is necessary to check and analyze the temperature effect of high-speed maglev track beam in the practical engineering.
