往复式压缩机橇小支管振动与抑制研究
|
摘要
分析了往复式压缩机橇小支管振动原因,利用Solidworks建立往复式压缩机橇小支管路三维模型,通过ANSYS Workbench软件对小支管路模型做了振动模态有限元分析,对比分析小支管在不同加固方式下的振动频率和模态。分析结果表明小支管附件刚度对其振动特性有很大影响,为避免发生小支管及附件的共振,除应加固主管道支撑外,还需对其小支管进行加固。
Vibration analyze the reason of small bore pipe of reciprocating compressor skid. The three-dimensional model of small bore pipe in the reciprocating compressor is established by Solidworks. The vibration mode finite element analysis of small bore pipe model is carried out by ANSYS Workbench software, and the vibration frequency and mode of small bore pipe under different reinforcement modes are compared and analyzed. The analysis results show that the stiffness of small bore pipe attachment has a great influence on the vibration performance. In order to avoid the resonance of small bore pipe, in addition to strengthening the main pipe support, the small bore pipe needs to be reinforced.
