Railway Wheel Squeal : Squeal of a Rotating Disk

概要

論文の詳細を見る
A steel rod was rubbed against the circumference of a thin steel rotating disk in its axial direction. A rotating disk serving as a railway wheel was clamped at the inner radius and free at the outer radius. A squeal occurred at low rotational speeds, when a nodal diameter mode of the disk was stationary in the space-fixed coordinated system. At relatively high rotational speeds, a squeal with a forward or a backward traveling wave was generated. Either of the two waves may occur depending on the vibration of the steel rod. Analytical responses of the rotating disk in both the disk-fixed and the space-fixed coordinate systems agreed with the experimental ones.
