Abstract
Inertial wave energy converter is a new technology to extract wave energy. The existing research mainly applies it to autonomous underwater vehicle or special wave power generation equipment. This paper explores the application of inertial wave energy conversion technology in ships to convert wave energy into electrical energy while reducing ship sway. Taking a work boat as an example, this paper first establishes the ship model in ANSYS and uses the panel method based on potential flow theory to obtain the hydrodynamic parameters of roll motion. The rolling random wave moment is simulated by equal frequency method. The mathematical model of the wave-ship-gyro system is described, and the system is simulated in the Simulink environment. Some physical limitations of the device and the classic passive PD controller of this system are introduced. The focus is on how to select the gyro angular momentum at the beginning of the design to match the ship to achieve the best power generation effect. Finally, the simulation results are analysed and the new power generation technology is evaluated.
