| Abstract | ||||
| The modal properties of fluid-structure system were investigated. A standard finite element software (COSMOS) was adapted to detect the modal properties of a tank partially filled with liquid. A concentrated mass element was added to the nodes of the wet part of the tank to resemble the fluid influence. Experimental work was conducted to help devise an empirical relation for the added mass relative to that of the fluid. The validity of the method was confirmed through laboratory measurements and comparison of results with the published work, which demonstrated good agreement. | ||||
