Abstract: The vibration reduction design of air conditioning compressor piping is an important part of the research and development process. Traditional suction pipeline design often achieves vibration reduction by adding bends around the compressor. In order to optimize the suction pipeline, a new type of suction pipeline was designed to be used with a pipeline vibration absorber, which can significantly reduce the difficulty of pipeline processing and material costs. And through HyperMesh finite element simulation combined with experiments, it has been proven that the vibration of the new pipeline is better than that of the traditional suction pipeline. After parameter optimization, the vibration absorber reduced the pipeline amplitude by 77.5% more than the shock absorber.
