| Abstract: | There are 3 ways to reduce refrigerator＇s noise： reducing the sound source,optimizing the sound delivery path,and repressing the response.In this paper,the second way is discussed only.Through the modal analysis of the back-plates of some Haier refrigerators,their natural frequencies and vibration modes are found.The optimal design of the back-plate structure is presented.The resonance between the back-plate and the entire refrigerator can be avoided and the noise can be reduced. |
