Wave Energy Absorption Through a Single Energy Absorbing Mechanism Applied to a Floating Body of Symmetrical Section

Abstract

Complete wave power absorption is studied by using a single energy absorbing mechanism and a two-dimensional floating body of symmetrical section. The energy absorbing mechanism and the floating body are articulated at a point away from the center line of the body. The energy absorbing mechanism is activated by the heaving motion of the articulate joint and absorbs incident wave power. The floating body can movein heaving and rolling, while the swaying motion at the joint is restricted. Concerning the device mentioned above, the conditions, which the characteristics of the energy absorbing mechanism and the floating body should satisfy for complete wave power absorption, are derived theoretically. Furthermore, a model test on wave power absorption is carriod out and the result of the test shows that complete wave power absorition is possible by using a single energy absorbing mechanism and a two-dimensional floating body of symmetrical section.
