碩士 === 國立成功大學 === 航空太空工程學系碩博士班 === 91 === In this thesis, the dynamic characteristics of rectangular Mindlin plates with rectangular openings is investigated by using the quadrature element method (QEM). First, we apply the formulation of differential quadrature to obtain the discrete algebraic governing equations of Mindlin plate elements, which are then assembled to get the discrete equations for the entire plate. Natural frequencies of rectangular, L-shaped and U-shaped plates with different boundary conditions are obtained, and compared with those obtained by the finite element method. Numerical results show the high accuracy and efficiency of the QEM for vibration analysis of rectangular Mindlin plates with rectangular openings.
