TLDR
This paper thoroughly evaluates the flexible deformation of shaft and bearing, time-varying nonlinear contact load, track irregularity, and bearing to establish a wheel/rail system coupling dynamics model and verified this theoretical model of the wheel–bearing–rail system dynamics.Abstract:
As the main bearing components of vehicle wheel/rail systems, railway bearings take on the main load of wheel/rail system. These bearings can be easily damaged after a long-term load, which causes ...read more

Vibration responses of rotor systems in diesel multiple units under dynamic spatial misalignments and base motions
TL;DR: Vibrations under deterministic and random base motions are numerically calculated using the Newmark Method and show that DSM is more nonlinearly sensitive to the deterministic base motion than rotor vibrations, and the converse is true when the base pitch motion is random in frequency.
