Abstract

Aiming at the noise radiation and propagation problem in the external sound field of power reactor, a simplified reactor model was established using ANSYS workbench, and the simulation model was imported into the acoustic software LMS virtual.lab, and the finite element mesh was divided by the direct boundary element method, the vibration of the reactor surface is simulated and calculated, finally, the characteristics of the noise radiation and the sound field are analyzed, and the noise value around the reactor is predicted to show that the sound diffraction phenomenon is very strong, the sound pressure value changes rapidly, and the relevant results can provide a corresponding theoretical basis for reactor noise reduction.
