抄録

A rotating disp is utilized in many industrial flelds, such as a magnetic memory disk and a rotational mixer, and higher rotational speed is needed to achieve high performance. However it is well known that a flexible disk rotating in a confined fluid undergoes unstable vibration when the rotational speed exceeds a critical one, and that the unstable vibration occurs due to the interaction between the flexible rotating disk and the swirling fluid flow around it. Up to now, I have studied experimentally the characteristics of unstable vibrations induced in a single flexible disk rotating in a confined fluid, and found that the unstable vibration exhibits different mode shapes depending on the rotational speed, and visualized the unstable vibration mode shapes. This paper deals with detailed experimental investigation of the influence of the gap width between the rotating flexible disk and the side-shroud wall on the unstable vibration characteristics of a flexible disk rotating in a confined fluid. It was found that the gap width is an important parameter for the unstable vibration characteristics.
