Comparison of Analytical, FEM and Experimental Modal Analysis of Plate for Free-Free Boundary Condition with Uncertain Parameters
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2015, Vol 12, Issue 1
Abstract
Modal analysis of plates has been an active research subject of engineering field. The plates are used for manufacturing many engineering structures such as in aerospace, mechanical, civil structures etc. This work attempts to present comprehensive comparison of modal analysis of square plate with free boundary condition. The first six natural frequencies of square plate with free-free boundary condition is first determined by analytical method. The modal analysis of plate is than solved by FEM using ANSYS 14.5 simulation. In this method the first six natural frequencies of plate are determined. Then the experimental setup is developed to identify the first six natural frequencies of plate. All the methods of finding the first six fundamental frequencies are compared. During comparison it is observed that all the six fundamental frequencies obtained by different methods are close to each other. Hence, from this it is clear that the results of analytical, FEM (simulation) and experimental methods are in agreement with each other.
