| Abstract: | With the increasing speed of the high-speed railway, it is extremely important to study the mechanical and vibration characteristics of all train components in detail to ensure its safety and comfort. The bogie is one of the most important components, because if there is a problem with the bogie, it will cause the train to deviate. Real-time strain data of the bogie during train operation can best reflect the real response of bogie. This paper studies the bogie based on real-time data. In order to ensure high speed and high efficiency of high-speed railways, the bridge and tunnel proportion of some high-speed railway lines is very large. There is little research on whether the mechanical response of a bogie is different when the high-speed railway passes through bridge, tunnel and normal ground. In this paper, the data of the bogie when the train is running on bridges and through tunnels is extracted for study. The corresponding stress spectrum has been established. |
