Abstract

The possibility of self-oscillations in the case of transverse vibrations of elastic homogeneous beams is investigated taking into account presence of dry friction in system. The problem is solved using examples of a beam suspended by one end on rotating shaft and a beam articulated at ends. The method of replacing original system by equivalent mechanical oscillation system is used.

Keywords
