The vibration and noise level of air condition compressor is one of the important performance index for the compressor quality. This paper focuses on a problem that the vibration amplitude of 4 octave at a particular frequency range is greater than that of 1 octave for the rolling rotor compressor. Through analyzing the frequency sweep and experimental modal, and identifying noise source, it is determined that structure resonance causes the happen of exceeding the standard for 4 octave. Meanwhile, two control methods for 4 octave vibration are proposed to increase the quality of accumulator and strengthen the stiffness of accumulator bracket. Moreover, experimental results show that these two methods improve the natural vibration characteristics of the compressor which effectively reduce the amplitude of 4 octave vibration, and the way to strengthen the stiffness of accumulator bracket produces smaller vibration response.
