| Popis: | 99 There are many vibration reduction techniques that have been studied for reducing vibration of simulated CD-ROM drive under high speed of rotation and read-write action of reader. Due to good vibration absorption, low cost and easy installation, many rubber dampers are being used as the absorbers. The frequency response of simulated CD-ROM drive system created by combining upper and lower steel plates and rubber damper is studied in this paper. ANSYS is used as the main tool to do the modal analysis of simulated CD-ROM drive system in order to find the mode shapes and the corresponding frequencies. In addition, Laser Doppler vibration is used as the experimental instrument to measure the resonance frequency of simulated CD-ROM drive system. The measured results are then verified with the analyzed results from modal analysis. It shows that the frequency response obtained from modal analysis by using ANSYS are very close to the measured results from Laser Doppler vibration, and the vibration is in the small range of 1.3% to 4.4%. The finite element analysis model can provide real contribution to the development and design of simulated CD-ROM drive system. |
