摘　　要：针对非能动核电站管道排气消声器的工作环境和技术要求,采用有限元分析软件ANSYS对多节扩张室加内插管的抗性排气消声器进行声传递损失和流体压力损失的数值仿真计算。分析了不同结构参数对消声器声传递损失、通过频率和压力损失的影响,并以此为依据,合理确定消声器的结构参数组合,得到性能较好的管道排气消声器。According to the working conditions and technical requirements for pipe discharge muffler in passive nuclear power plant,the numerical simulation was used in analyzing sound transmission loss and fluid pressure loss of multi-section expansion muffler by finite element analysis（FEA）software ANSYS.The effect of different muffler structural parameters on sound transmission loss,passing frequency and pressure loss was also analyzed.Based on the analysis results,a reasonable combination of the muffler structural parameters was determined,and a pipe discharge muffler with good performance was obtained.
