Free Vibration Characteristics of Thermally Loaded Rectangular Plates

Abstract:

This paper reports on experimental and finite element analysis of the free vibration analysis of three rectangular plates under thermal load. The materials of the three rectangular plates were steel, aluminum and stainless-steel, respectively. The dimension of the plate was 0.1 x 0.1 x 0.002 m. Halogen lamps were used for thermal loading. A PCS (Power Control System) electric control system and a scanning vibrometer (Poly Tech) for frequency response function’s (FRF’s) acquisition were used. The applied temperature conditions were from room temperature to 300oC in 50oC steps. The boundary condition was a free-free condition using bungee cord and one entire side of the plate was heated. ABAQUS was used for FEM analysis. At first, the heat transfer analysis was conducted for each temperature condition and the modal analysis afterwards. The FEM model was verified by comparing experiment and FEM analysis. The FEM model for the modal analysis of thermally loaded plates could be verified.
