石化能源的枯竭使得人們尋求著替代能源方案，現今的再生能源有太陽能、風能、波浪能等，但是製做太陽能板與風力發電機所費不貲，故本論文使用平板型線性發電機的概念發展一套利用船舶運動的波浪能獵能系統，用以擷取由波浪能造成的船體運動能量，再將此動能轉換成電能，為乾淨能源提出另一項不同的選擇。本文以船舶非線性六度運動方程式分析不同海況下的時程領域船體運動，經由程式計算出瞬時的縱搖或橫搖角度，在以此為基礎之下，利用動力學以及數值方法計算動子之瞬時加速度、速度以及位移，並且結合法拉第定律計算瞬時的感應電動勢，搭配二維有限元素軟體(2D-FEM)求解方程式中的磁通密度變化率，計算出不考慮摩擦力時的理想感應電動勢，以此為依據之下，推算可能的功率輸出。本文另外也實際完成一套獵能系統模型，以六軸運動平台為實驗載具，此平台可依船體運動程式所計算的瞬時縱搖或橫搖角度進行作動，同時於作動過程中量測線圈的感應電壓，最終計算出實驗的功率輸出。本文在三種不同波浪條件時，模型尺寸的功率實驗值可達約0.124W，在不考慮摩擦力的因素下，依實用狀況將模型放大三倍後，預估可以有1.675W的輸出。

The serious consumption of the mineral oil makes people seek for the alternative energy. Nowadays, there are many types of alternative energies developed in the world, such as solar power, wind power, wave power, and so on. However, it’s quite expansive to manufacture the solar power board and wind power generator. 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 thesis uses the 4th Runge Kutta method to simulate the ship’s pitch and roll 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 power can reach 0.124mW according to the present three wave conditions. If we enlarge the model to the realistic scale, the power might reach 1.675W.
