摘要
空调压缩机工作时会间歇性的吸气和排气,这将会导致压缩机产生相应的振动,而振动将会传递到与之相连的管路上,管路在长期振动下容易断裂导致冷媒的泄漏。通过有限元仿真软件对管路系统进行了模态分析和谐响应分析,并通过增加消声器和增加管路壁厚的方法对管路进行减振分析,通过优化管路系统降低管路振幅,提高管路使用寿命。
The air conditioner outdoor unit of piping system will produce corresponding vibration.The pipeline is easy to break under the long-term vibration,which leads to the leakage of refrigerant.In this paper,the modal analysis and harmonic response analysis of pipeline system are carried out by finite element simulation software.The vibration reduction of pipelines is analyzed by adding mufflers and increasing the thickness of pipelines.By optimizing pipeline system,reducing pipeline amplitude and improving pipeline service life.
