  • Online:2010-03-25 Published:2010-03-20

Abstract: The phenomena of self-excited vibration by dry friction is studied and the analytic expression is obtained. So its vibration curve and phase plot show the physical causes of a string-bow musical instrument sending out sweet tone.

Key words: rest friction, slipping friction, simple harmonious vibration, turning-vector circle
