There is a noticeable hum from the inverter board of LCD TV when in operation. In this study, we investigate the source and the characteristics of this noise for the inverter board of LCD TV using measurement of vibration and noise. Modal analysis of vibration and noise is visualized for identification of noise sources and transmission vibration. The main source of noise was the transformer of the LCD TV inverter. A noise reduction was achieved by damping the structural elements.

Al6061 and Sus304 materials are bonded by using thermal bonding technology. Al6061, Sus304 and thermal bonded Al6061/Al6061 and Al6061/Sus304 materials are characterized by using mechanical and electrical measurement. Especially the experimental characteristic data of thermal bonded Al6061/Al6061 and Al6061/Sus304 are not well known until today. We have investigated on Al6061, Sus304 and thermal bonded material. The thermal bonded material Al6061/Al6061 and Al6061/Sus304 can be used for the LCD frame and the other electrical products. For the future, we expect that the more various experiments should be needed to carry out for the data accumulation in the bonded new materials.

The elastic coupling system, which has a non-linear spring as an element and pendulum type absorber(PA) is studied numerically. The behavior ofthc elastic model shows non-lincar curves which is qualitatively similar to those of real clastic matcrials. The frequency-response curves show non-linear character and absorber effect.
