Abstract

Abstract This paper presents a theoretical analysis of the vibration and stability of rotating slicing blades, free at the inner radius and clamped along the outer radius. Natural frequencies are determined as functions of the rotational speed of the blade. The frequency-speed diagram obtained is quite different from that of the ordinary clamped-free circular sawblade. It is found that the blade has three types of instability. The first one is the run-out effect which is frequently observed in the clamped-free blade. The second and third ones are the divergence and flutter types of instability which are not observed in the ordinary blade.
