It is generally known that the groove on tire tread can increase friction force between and road surface under wet condition because of improvement drainage performance. Although wheel actual railway rolling stocks have a turning trace like tread, characteristics tangential contact wheel/rail not clarified in detail. In this study, measurement using pair small cylindrical specimens was carried ...

Maintenance of Railway rolling stock is usually scheduled based. However, the mechanical parts, especially wheelset may wear down prematurely due to several factors such as excessive braking and traction forces environmental conditions. This makes maintenance less effective sometimes it results in derailments. paper presents a deep learning-based technique detect wheel conditions so that can be...

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...
