Abstract

Recognition of the dynamical behavior and vibrations of marine structures, submerged in vicinity of the WATER FREE SURFACE, is one of the most important issues in the design of marine structures. It is obvious that physical properties of the ambient fluid have some influence on vibrational frequencies of the structures. For the structures that have been exposed under the influences of asymmetric environmental conditions, prediction of their dynamic behaviors is more complicated. In this paper the effects of IMMERSION DEPTH on first NATURAL FREQUENCY of a bounded CIRCULAR PLATE that was placed parallel in the vicinity of the water surface, are studied numerically and experimentally. The techniques used for exciting the plate and measurements of natural frequencies are innovations of this research. Numerical solutions are done using ABAQUS software. Comparison of the numerical and experimental results shows a good consistency. The investigations showed that increasing the IMMERSION DEPTH, the ratio of the depth to plate diameter reached to a certain value and the natural frequencies were also decreased. After that it remained constant while the IMMERSION DEPTHs of plate were increased.
