This study investigates acoustic radiation of rectangular Mindlin plates in different combinations of classical boundary conditions. A set of exact close-form sound pressure equations are given for the first time using the so-called Mindlin plate theory (a first-order shear deformation theory) for the plates having two opposite edges that are simply supported. The other two edges may be given any possible combination of free, simply-supported and clamped boundary conditions. It is assumed that mechanical in-plane loading occurs on the plate structure. In order to study the transverse vibration of moderately thick rectangular plates, the dimensionless equations of motion are derived based on the Mindlin plate theory. Structural–acoustic coupling is implemented for vibrating plate models. The radiation field of a vibrating plate with a specified distribution of velocity on the surface can be computed using the Rayleigh integral approach. The acoustic pressure distribution of the radiator is analytically obtained in its far field. Additionally, the influence of six possible combinations of boundary conditions, foundation parameters, loading cases, aspect ratios and thickness ratios on the sound pressure are examined and discussed in detail. 2009-11-12T02:48:02Z 2009-11-12T02:48:02Z 2009-10-11 Working Paper p.13F 1 - 13F 7 978-967-5415-07-4 http://hdl.handle.net/123456789/7241 en Proceedings of International Conference on Applications and Design in Mechanical Engineering 2009 (iCADME 2009) Universiti Malaysia Perlis
