Abstract
Thin rotating disks are fundamental elements in numerous machines such as turbines, circular saw plates or disk brakes. When the disks rotate, they are often subjected to transverse vibrations. These vibrations decrease the mechanism's capabilities. It is significant to know the disk's vibratory behavior in order to develop a vibration decreasing system. The present paper proposes an experimental method to identify and locate the nodal diameters of a rotating disk. This method can be integrated into a global process to decrease the vibrations.
