| Wave power generation technology has a long history and a promising future.Consistent with the design concept of green ship,wave power generation applied in ships is provided in this paper,which would decrease the operating cost of ships and be of benefit to the environment.Based on the analysis about research progress of wave energy generation technology,the feasibility of this kind of device,the characteristic of the ocean squid jigging ship and wave resources of squid fishing ground,a newly wave energy device of ocean squid jigging ship is designed.The device is made of flexible material,and has the characteristic of low costs,safe and environmental protection,simple structure and convenient maintain,easy to be collected,and applicable in wide open ocean area.The motion mathematic model of the device is established by using the second kind of Lagrange kinematics equation.Then,force analysis is carried out on the device,and WAMIT software is used to calculate the wave force,torque,added mass coefficient A,radiation damp coefficient B,etc.And the mathematical model is solved by using the runge-kutta method.After that efficiency of the wave capture device is simulated.The floating bodies of the device were designed with resonance principle.By comparing wave capture width ratio of the device with arm in range of a wavelength being simulated,it is found that,wave capture width ratio of the device is the highest when the arm length is half of the wavelength.Based on that,20 kinds of wave energy device layout manner of ocean squid jigging ship are designed.By the method of the numerical simulation,the optimum radius of the floating body of these devices is 2m,and the maximum annual average power among these devices is 136 kW,which can save about 10% of the fuel consumption for the ocean squid jigging ship. |
