In order to study the influence of an integration time step on dynamic calculation a vehicle-track-bridge under high-speed railway, (VTB) coupled model is established. The accuracy and stability different speeds or track regularity states studied. irregularity further analyzed by using spectral characteristic sensitive wavelength. According results, disparity among effect VTB at very small. Hig...

To improve the quality of track maintenance work, it is a desire to estimate vehicle dynamic behavior from geometry irregularities. This paper proposes deep learning model predict responses (e.g., vertical wheel-rail forces, wheel unloading rate, and car body acceleration) using techniques. In proposed CA-CNN-MUSE model, convolutional neural networks (CNNs) are used learn features irregularitie...
