Abstract:Focusing on the mechanism of the abnormal phenomenon of rail corrugation on the low rail of small-radius curve section of Guangzhou–Zhuhai intercity railway, the distribution regularities and the track irregularities are studied through the overall and local field surveys. Then, the dynamic model of vehicle-track system on the section is established to explore the wheel-rail dynamic characteristics. Next, the relevant finite element model of the wheel-rail system and the wear model of rail corrugation are esta… 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.
