2022年9月1日 · With the development of high-speed maglev trains, a new generation maglev train, designed for a speed of 600 km/h, has been invented in China. The aerodynamic effect induced by a train passing through a tunnel at such a high speed is becoming a big challenge for researchers on train/tunnel aerodynamics [3]. How to explore the mechanism of this ...

2021年12月29日 · After a high-speed train travels through a railway tunnel, the aerodynamic pressure waves are generated and exert loads on the tunnel lining. The interactions between the running train and the air inside the tunnel produce pressure waves that propagate along the tunnel at the speed of sound.

High-speed trains can maintain top speed in the tunnels. A train traveling south will pick up speed as it leaves Gilroy, reaching up to 220 miles per hour, and will continue at that speed through the tunnels and into the Central Valley.

2024年11月5日 · Several factors influence the aerodynamic effects of high-speed trains passing each other in tunnels, including train speed, tunnel cross-sectional shape, tunnel length, and line...

2022年5月1日 · When a high-speed train passes through a shield tunnel, it is important to understand what aerodynamic effects it will produce and what differences will exist between the aerodynamic effects in a molded-lining tunnel and a shield tunnel.

2021年7月1日 · This investigation deals with numerical solution of complex aerodynamic interactions induced by a high-speed train (HST) entering and passing through tunnels with a closely adjacent gap and without in between.

2024年4月4日 · Aerodynamic characteristics produced by high-speed train associated with tunnel length are studied using numerical method. The input parameters, which are adopted in simulation, are verified with the on-site monitoring obtained by other researchers.

2008年11月2日 · An introduction to the Mechanical/Electrical and ventilation systems needed for the design, construction and operation of long High Speed Rail (HSR) tunnels. Content may be subject to...

2023年7月14日 · After decades of research in the field of high-speed railway technique, technology of running high-speed trains at the velocity level of 350 km/h gradually become mature. It is of great importance to capture the variation regular of aerodynamic parameters in the situation that the high-speed train runs at a higher speed level.
