Abstract: By studying the resonance problem of the compressor pipe, the optimal method of vibration reduction for pipe is determined by modal simulation and modal control theory in this paper. In order to prove the effectiveness of the method, the original scheme and the optimized scheme were applied to the product at the same time to reduce the vibration of the compressor pipe. It was found that the vibration response results of the optimized scheme were significantly smaller than the original scheme, and the amplitude is about 70% lower. Thus, the feasibility of the method was verified for vibration reduction of compressor pipe.
