Abstract

The present research applies the concept of flat linear generator to develop a wave energy harvester which is caused by the ship motion in waves. The device can harvest the energy due to the ship motion in wave and turn the motion energy into electricity. The concept offers another different choice for green energy. The paper uses the 4th Runge Kutta method to simulate the ship's motion and the mover's acceleration, velocity and displacement are also calculated without considering the friction on the slope plane. By combining the Faraday's Law and the mover's motion, we can get the EMF from the wire in six different conditions. Also, we use the 2-D FEM program to solve the flux density per meter. Thus, we can obtain the EMF and calculate the system's power. Moreover, we create a real harvester system model and take the platform base manipulator to simulate the ship motion in wave to measure the voltages and eventually we can calculate the power of the model device. The wave energy harvester has the advantage of small-size, manufacturing and modularization, which can also be extended to assist the power supply of the fishery purpose.
