It is known that chatter vibration of a cleaning blade occasionally causes a squeaking noise. This reasearch aims to investigate the basic characteristics of the motion of the blade, as the first step in determining the cause of the chatter. First, an elastic beam model is presented, and its governing equations and boundary conditions are derived. Next, the static state is discussed, with emphasis placed on the effect of friction. Finally, an experiment is conducted using a simple apparatus in order to verify the properties of self-excited vibrations.
