摘　　要：针对压缩机传统缓冲器对管路脉动抑制效率低的问题,基于ANSYS有限元分析软件对压缩机管路系统进行流体压力脉动分析与模态分析,对管路系统结构进行优化。压力脉动分析结果表明,缓冲器进口添加侧支吸纳器后,管路系统的压力脉动得到抑制。模态分析结果表明,由于管路的机械固有频率落在压缩机固有频率共振区内,增加防振管夹后可以提高管路的机械固有频率,从而避开压缩机激发态共振区,有效地控制了压缩机管路系统的振动。In order to improve the weak suppression of pipeline pulsation caused by the traditional buffer of compressor,and the analyses of the fluid pressure pulsation and the modal of the compres-sor pipeline system are carried out based on ANSYS finite element analysis software,the structure of the pipeline system is optimized.The results of analysis of pressure fluctuation show that the pressure fluctuation of the pipeline system is suppressed after the side branch absorber is added to the inlet of the buffer.The results of modal analysis show that since the mechanical natural frequen-cy of the pipeline falls in the natural frequency resonance zone of the compressor,it can be in-creased by adding the anti-vibration pipe clamp,so as to avoid the excited state resonance region of the compressor and effectively control the vibration of the compressor pipeline system.
