Abstract

Journal of Vibration and Control, Ahead of Print.
Owing to its low axial force and high load-bearing capacity, herringbone gear transmission shows significant potential for application in high-speed heavy-haul railway transportation. In this study, a rigid-flexible coupled dynamic model of a high-speed ...
