Taking an industrial gas turbine intake pipeline as the research object, the acoustic field of the intake pipeline is simulated and analyzed by using acoustic finite element method, and the internal acoustic field and transmission loss of the intake pipeline are calculated. Through simulation analysis, it is found that the transmission loss curve of gas turbine intake pipeline fluctuates greatly, and the frequency bandwidth of the peak muffler is narrow. The conclusions obtained provide a theoretical basis for optimizing the structure of industrial gas turbine intake pipeline.
