Experimental Modal Analysis of Compressor Vibration Isolating System Based on LMS Test.Lab

摘要：

　　In order to reduce vibration and noise of the compressor used in small and medium-sized refrigeration unit,this paper designs different vibration isolating systems and carries out experimental modal analysis based on LMS Test.Lab Impact Testing software.The comparison results of modal parameters of four different vibration isolating systems show that the natural frequency of single-layer vibration isolating system is higher than that of non-isolation system and effectively avoids the second order resonance frequency.Furthermore the natural frequency of double-layer vibration isolating system has reduced due to the additional middle-mass.And the systems natural frequency decreases obviously with the increase of middle-mass which is far from resonance frequency and significantly improve the effect of vibration isolating system.
