Vibration Control of a CD-ROM Feeding System Using Electro-Rheological Mounts

Abstract

This paper presents vibration control of a CD-ROM (compact disc-read only memory) drive feeding system using an electro-rheological (ER) fluid mount. An appropriate size of the ER mount, which is adaptable to existing CD-ROM drive feeding system, is designed and manufactured on the basis of Bingham characteristics of an ER fluid. After verifying that damping force of the ER mount can be tuned by the intensity of electric field, the ER mount is installed to the drive feeding system. The governing equation of motion is then derived, and a skyhook controller is designed to effectively control unwanted vibration caused from external excitation. The controller is incorporated with the hardware-in-the-loop simulation (HILS) methodology, and vibration control performances are evaluated in both frequency and time domains.
