Study On Hydrodynamic Response Of Buoy With Shock Absorber

This paper investigates the hydrodynamic response of a new buoy with shock absorber.In this multi-body system,the catenary with pretention is used for mooring and spring system is applied to connect multi-bodies.Based on wave radiation and diffraction theory,the motion equation of multi-bodies is set up by boundary element method.The wave transmission and reflection coefficients,the wave exciting force are obtained.The added mass and damping of individual body is analyzed,the motion response of this type buoy is discussed.
