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

Quasi-Harmonic Friction-Induced Vibration [PDF]
Journal of Lubrication Technology, 1970 A theoretical and experimental investigation of quasi-harmonic friction-induced vibration is reported. The vibration is of near-sinusoidal form and is solely governed by dynamic friction forces. However, the friction-velocity curve must be of a particular shape for the vibration to occur.

Friction-induced vibration characteristics of water-lubricated rubber bearing
Zhongguo Jianchuan Yanjiu, 2018 [Objectives] The stern tube rubber bearing is an important part of marine propulsion systems. However, under unfavorable low-speed, heavy duty and partial high-temperature working conditions, bad lubrication can occur and cause friction-induced vibration.

Tactile perception by friction induced vibrations [PDF]
Tribology International, 2011 When a finger moves to scan the surface of an object (haptic sensing), the sliding contact generates vibrations that propagate in the finger skin activating the receptors (mechanoreceptors) located in the skin, allowing the brain to identify objects and perceive information about their properties.
