Experimental Modal Analysis and Modal Reproduce Experiment Research of a Chladini Plate

By means of ANSYS Workbench, different materials, dimensions and shapes of the Chladni plates are simulated. The natural frequency and Modal are obtained so that the chladni plate is determined and manufactured, that is used in the experimental research. Then, modal analysis test is conducted by Experimental modal analysis, the resonance and modal characteristics of the plate between 1Hz to 1000Hz are identified. Finally, Modal reproduce experiment is conducted under the acoustic excitation. Experimental and analytical results show that the finite element analysis, experimental modal analysis and Modal reproduce experiment basically have the same results.
