目前玻璃纖維（FRP）漁船及大型鐵製漁船上所採用之漁船水密艙口蓋，其主要目的是為保持漁貨之新鮮避免冷媒之外洩。因此，漁船水密艙口蓋之密封性、耐蝕性即顯得非常地重要。然而現行之漁船水密艙口蓋尚無設計規範可資參考，從目前使用之情況分析發現，艙口蓋普遍存在操作靈活性不佳、防密封性差、使用年限低、操作安全顧慮、艙口蓋本體笨重等缺失。
本計畫旨在針對現有漁船艙口蓋之缺失，重新設計漁船水密艙口蓋系統。本研究擬使用之主體材質係為耐海水腐蝕性佳之鋁合金，整個系統主要藉由一組省力式機構，並利用電腦繪圖軟體進行系統零件之立體模型建製，輔以電腦分析軟體進行傳動機構桿件合成、機構動畫模擬及機構干涉分析，最後完成一個雛型製作，並安裝在漁船上進行實船測試，並做必要之修正。本計畫開發完成之密閉式艙口蓋設計系統，可提供爾後漁船設計者在進行艙口蓋設計時之參考依據。

關鍵字：艙口蓋、鋁合金、省力式機構、電腦輔助分析 Currently, the sealed hatchway cover used in FRP and large iron ships is to keep the freshness of aquatics and to prevent cool-media from leakage. Therefore, the water tightness, corrosion resistance, operation flexibility, and safety are quite critical on the application of sealed hatchway covers. At this moment there is lack of design standard to follow up in the development of hatchways. However, it has been found that some disadvantages are existed in the current application. For example, the operation flexibility and water tightness are not good enough; the service life is limited; the safety on operation is concerned, and the hatch is heavy.
The aim of this project is to develop a new sealed hatchway cover system to overcome the existed drawbacks. The material adopted in the new system will be the aluminum alloy with good property on corrosion resistance. The whole system uses a set of less-strength mechanism. It not only involves the 3-D models for all components used in the system, generated by computer graphic software, but also applies computer-aided engineering (CAE) tools to analyze the linkage assemblage, animation, and interference of the developed mechanism. Finally, a prototype will be manufactured and installed on a fishing boat to conduct the performance test. The modification will be followed if necessary. As a result, the design methodology developed in this project is expected to serve as a reference for designing system hatchway covers in the future.
