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 ...

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.
