The vibro-noise of a homemade centrifugal pump excited by the internal unsteady flow are numerically investigated. The unsteady flow field is solved by using the shear stress transport $\mathrm{k}-\omega$ model. The computed results are adopted to extract the pressure fluctuations on the inner walls which are fed to the structural analysis to excite the vibro-noise. The sound pressure level (SPL) of the internal noise of the centrifugal pump is experimentally obtained, confirming the effectiveness of the numerical method. In this paper, the structure of perforated plate is designed to optimize the vibro-noise caused by the pressure fluctuations of the fluid. It is found that the perforated plate has a significant effect on suppressing the vibro-noise of the pipe under the studied conditions by numerical simulation.
