Modal Performance Analysis of Compressor for Active Control of Acoustic Radiation

Compressor has a complex internal structure and contains various kinds of motion mechanism. At present, research on compressor’s vibration and sound radiation characteristics is insufficient. In this paper, structure and sound radiation modes of control objects are analysed by mode analysis. Explore the mode distribution law and correspond the structure mode to the sound radiation mode. On this basis, by suppressing the vibration mode, the influence is transmitted to the acoustic domain to realize the active control of sound radiation of the structure as a whole.
