Abstract: While enhanced rainbands progressed northward in East Asia from June to August during the regular El Niño decaying summer, strengthened rainbands were only observed in the earlier summer and disappeared in August in the ...

Abstract: Rail corrugation, a common defect of rails, causes a high frequency self-oscillation effect in track slabs when there is an external load. In order to analyze the influence of multi-scales of rail corrugation on the dynamic ...

Abstract: The purpose of this study is to analyze the rotational speed characteristics of a spherical turbine start-up process, and the rotational speed characteristic of the spherical turbine is studied by numerical simulation. In ...

Abstract: As railway maintenance increasingly requires strict inspection and accurate repair, it is urgent to establish a reasonable assessment method for identifying the risks in high-speed railways. Severe track irregularities can ...

Abstract: A novel fiber-reinforced calcium silicate board was prepared from fly ash. The effects of compression pressure, pulp fiber content, and cement content on the flexural strength and thermal conductivity of the fiber-reinforced ...

Abstract: The real-time identification and early warning of the state of the track are significant to keep the high-speed railway (HSR) safe, stable, and comfortable. This paper proposes a new risk identification method based on the ...
