Abstract:Tunnel passing in high speed produces aerodynamic load on railway train, which brings about fatigue failure on the car-body, and damages passenger comfort due to interior penetration of the alternating wave. Experimental simulation of the alternating load remains a challenge concerning its accuracy and reliability. In this work, experiment approaches in terms of air compression and air suction were developed, in an attempt to simulate the air pressure variation when the train runs through tunnels. Pros and con… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
