초록
In this paper, we present our method of controlling the transmission path of compressor vibration to reduce the vibroacoustic of refrigerator. Firstly, to reduce the vibroacoustic radiated from compressor _ mount system, main transmission path was found experimentally and applied partial contact to transmission path to minimize the transmissibility from compressor operation to base plate. In order to verify our method, we designed changing of the connection part between grommet and base plate. Through experiment with modified connection part, we certificate experimentally the noise reduction of refrigerator. Finally, we apply previous connection part to grommet inner shape to enhance the effect of the system. From experimental results, we make certain the possibility of noise reduction of refrigerator through this approach.
