Self-excited Vibration of Ink Rollers

ACC Journal, 2021
A vibration having a character of self-excited chatter oscillation known from machine tools is observed during intermittent motion of ink rollers of offset printing machines. This vibration occurs under specific operating conditions and is often accompanied by an increased noise level.

Self-synchronization characteristics of a class of nonlinear vibration system with asymmetrical hysteresis

Journal of Low Frequency Noise, Vibration and Active Control, 2020
The self-synchronization characteristics of the two excited motors for the nonlinear vibration system with the asymmetrical hysteresis have been proposed in the exceptional circumstances of cutting off the power supply of one of the two excited motors ...

Reduced-order modelling of vortex-induced vibration of catenary riser

, 2009
A new reduced-order model capable of analyzing the vortex-induced vibration of catenary riser in the ocean current has been developed. This semi analytical-numerical approach is versatile and allows for a significant reduction in computational effort for

Influence of anisotropic support of tool for self-excited chatter in end-milling

Nihon Kikai Gakkai ronbunshu
In end milling, chatter vibration generated during processing becomes a problem in processing accuracy. Chatter vibration is classified into forced chatter and self-excited chatter depending on the cause of the vibration.
