Abstract
According to the working conditions and technical requirements for pipe dis‐charge muffler in passive nuclear power plant ,the numerical simulation was used in ana‐lyzing 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 muf‐fler structural parameters was determined ,and a pipe discharge muffler with good per‐formance was obtained .关键词
