Vibration of flexible rotating disks

Abstract

Rotating disks are key components of many rotating machines, such as computer hard disk drives, circular saws, and disk brakes for automobiles and aircraft landing gears. Mathematical models of these systems consist of four elements: disks, spindles, bearings, and sliders. Depending on the application, the disks, spindles, and bearings can be modeled as rigid or flexible. The sliders are often modeled as a stationary spring-mass-dashpot system in contact with the rotating disks. This paper reviews recent vibration research on single and multiple flexible rotating disks interacting with spindles, bearings, and sliders. Systems with rigid rotating disks are not included in this review.
