A Development of the Vibration Absorber and Damper for Vibration and Noise Reduction of the Computer

PC의 진동/소음 저감을 위한 쿨링팬의 동흡진장치 및 절연장치의 개발

The purpose of this study is to reduce the vibration of the computer by developing the vibration absorber and damper. The eccentricity of the cooling fan causes the vibration of the computer. We designed the material properties of the vibration absorber by FEM model within operation frequencies of the cooling fan. We experiment the overall analysis and system analysis. The vibration of cooling fan is measured by using a laser vibrometer. The result shows that the proposed vibration absorber and damper reduce the vibration of the computer.
