Vibration characteristics of computer stacked disks and head assembly

  • 초록

    A stacked multi-disk with read/write head assembly was investigated. The interference of head assembly on the spinning disks was modeled by stationary springs intervening between disks. The receptance method was then applied to join the spinning disks and the stationary springs. A general, recursive equation for natural frequency of a disk-head system was derived. Numerical examples followed for the cases of 3 to 6 stacked disks. The results showed that even for weak spring coupling, the changes of mode shapes were very significant and the changes of natural frequencies were slight. The effects of spring stiffness, location, and disk spinning speed were examined as well. The spinning speed was seen to pull the frequency loci to pass through the crossings of a single disk's frequency curves and there existed a curve-veering phenomenon.
