Detailed mechanism of self-excited vibration of a plate supported by air pressure
Nihon Kikai Gakkai ronbunshu, 2021 This study presents a dynamic stability analysis of the self-excited vibration of a plate supported by air pressure. In the analysis, the unsteady fluid force acting on the plate surface is calculated based on the theory of two-dimensional leakage flow ...

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.

On the influence of external stochastic excitation on linear oscillators with subcritical self-excitation applied to brake squeal [PDF]
, 2019 A characteristic of linear systems with self-excitation is the occurrence of non-normal modes. Because of this non-normality, there may be a significant growth in the vibration amplitude at the beginning of the transient process even in the case of ...

Quasi-particle random phase approximation with quasi-particle-vibration coupling: application to the Gamow-Teller response of the superfluid nucleus $^{120}$Sn [PDF]
, 2016 We propose a self-consistent quasi-particle random phase approximation (QRPA) plus quasi-particle-vibration coupling (QPVC) model with Skyrme interactions to describe the width and the line shape of giant resonances in open-shell nuclei, in which the ...
