本文研究目的是提供液壓式波浪發電裝置設計方法，其中模組化設計能夠減少維修，増加波能擷取裝置壽命與降低成本。波浪不規則性，使往復式泵行程終點需設置防碰裝置。波長、波幅與波速對浮體提供擷取波能大小影響，湧浪的長波較適合波能擷取，浮體需設置襯墊增加阻后效應，減少小浪花的不規則輸出影響。波能擷取裝置的運動分析，可瞭解液壓裝置的質量、阻后、等效彈簧勁度與波浪頻率對浮體擷能影響。

In the purpose of this research, it is provide a design method for the hydraulic model of the wave energy converter, modular design can reduce the maintained number, and increase the useful life of the wave energy converter and reduced cost. In irregular wave, the stroke of the reciprocating pump must have a protected instrument. Wavelength, wave amplitude and wave velocity can make an effect to obtain the wave energy. In a dynamic analysis of the wave energy converter, it would explain the effect from the mass, damping, equivalent stiffness and wave frequency.
