【Abstract】 This paper applies weak_interaction method to analyze fluid_structure interaction. The factors that affect the added mass of structures in fluid environments are discussed, and then the general method for calculating kinetic energy of fluid is derived. The added mass of a cylindrical column and a membrane structure are calculated. It is concluded that added mass significantly influences the membrane structures on their dynamic properties. 更多还原
