Abstract: Wave energy, with its wide distribution and abundant reserves, has considerable application prospects. This paper studies the basic structure of the wave energy conversion device, and analyzes the current situation of the maximum output power of the device under the wave energy according to its mechanism. At the same time, the heave motion model and pitch motion model of the device under the force condition when waves are generated at the sea level are studied, and the correlation and restriction conditions of the two motion models are found by using Newton's second law of motion and Law of differential moment of inertia; On this basis, the output power of the device under two different motion states is obtained by integrating the power. Finally, the final power output model is built by adding the two powers, and the corresponding component parameter results when the device generates the maximum power are found.
Keywords: force analysis; Newton's second law of motion; Law of differential moment of inertia; power integration
