Abstract

The application developments of a mixed finite element method for transient dynamic analysis of fluid-structure interaction systems (FSIS) in maritime engineering are summarised in this paper. Following the mathematical equations governing generalised FSIS, three problems involving maritime engineering, developed in Marstruct Project, are presented to illustrate the applications of the developed numerical method. Problem 1 investigates the sloshing frequencies of a liquid storage tank and its dynamic response excited by the El Centro earthquake data. Problem 2 analyses the dynamic response of a LNG tank-water interaction system subject to an explosion pressure wave on a water boundary. Problem 3 considers the dynamic response of a structure-acoustic volume interaction system subject to human footfall impacts, which may be used to simulate ship deck vibration caused by human footfall loads to obtain a comfortable living environment of passengers. The numerical results are discussed and analysed to provide the related guidelines for the designs of maritime products involving fluid-structure interactions.
