Simulation analyses of progress process of rail corrugation
Nihon Kikai Gakkai ronbunshu, 2019 Rail corrugation is such phenomenon that roughness patterns of approximately regular wavelengths are formed on the rail running surface by trains running, and cause the vibration and the noise.

International Journal of Naval Architecture and Ocean Engineering, 2021 To investigate the mechanism of friction-induced vibration and noise of ship water lubricated stern bearings, a two-degree-of-freedom (2-DOF) nonlinear self-excited vibration model is established. The novelty of this work lies in the detailed analysis of

Role of vibrations in the jamming and unjamming of grains discharging from a silo [PDF]
, 2009 We present experimental results of the jamming of non-cohesive particles discharged from a flat bottomed silo subjected to vertical vibration. When the exit orifice is only a few grain diameter wide, the flow can be arrested due to the formation of ...

A Generalized Approach to Coupled Nonlinear Vibrations of Continuous Systems [PDF]
Mathematical and Computational Applications, 1997 A mathematical model covering many practical vibration problems of continuous systems has been proposed. The equations of motion consist of two nonlinearly coupled partial differential equations. The quadratic and cubic nonlinearities as well as the linear part of the equations are represented by arbitrary operators.
