NUMERICAL INVESTIGATION OF ACOUSTIC BEHAVIOUR OF STIFFENED CIRCULAR ANNULAR PLATE UNDER THERMAL ENVIRONMENT AN ANALYSIS USING FEM

In mechanical components, circular plates with patches are frequently utilized. The inherent frequencies and mode shapes of a circular plate are significantly altered when a patch or hole is present. This research uses finite element analysis (FEA) to study the acoustic behavior of annular circular plates with numerous circular patches. The temperature is maintained at a steady level. The impact of sound power level on aspect and radii ratios is examined for several annular circular plates. These plates are analyzed using the free-free and clamped-free boundary conditions. The parametric investigations are carried out, and the outcomes are examined and noted.
