Based on the AQWA numerical simulation software,analyzing the sensitivity of the parameters of the dynamic characteristics of the Heaving Buoy Wave Energy Convertor,the key parameters are proposed for optimal design.In consideration of the environmental conditions of the actual sea area,the structural dynamic characteristics optimization proposes are put forward to calculate the critical value of the key parameters which affect the structural dynamic characteristics,and checks up the structure of optimal design.The result shows that the one of key parameters that affects the structural dynamic characteristics is the stiffness of the tension cable.As the stiffness of the tension cable is increased to avoid the resonance area,the structural kinematic parameters are reduced obviously.The results of this study can provide a reference for the optimization design of mooring system for heaving buoy wave energy convertor.
