摘要

空氣幫浦長期使用魚水族繁殖業與汙水處理及綠色能源中的燃料電池中佔有有重要地位。然而對於空氣幫浦需要滿足全年無休且無間斷的供應空氣，以導致如何使空氣幫浦中關鍵零組件具有較長壽命，流量更大，且較低成本維修零件更換方便，是現今各空氣幫浦大廠朝向目標。
本研究應用田口法(Taguchi Method)以最低成本改良為出發點，尋找出最佳化組合，分別對於空氣幫浦的閥門、避震腳、主體結構，利用有限元素分析軟體ANSYS 的模擬分析，提出一套設計參數最佳化設計的方法。
本研究的初步成果顯示，未來可以此種方式，結合田口法與有限元素軟體ANSYS 建立空氣幫浦最佳化設計的專家系統(Expert System)，提供工業界在設計之參考，以縮短產品開發的時間。

Air pump has been used and played an important role on aquarium breeder, polluted water treatment and green energy of fuel cells for a long time. One of ultimate goals of air pump is to supply of air flow steadily and continuously all year round. To reach this goal the major challenge of the air pump manufacturers is to design the key components of the air pump with a longer life. In addition, needs of higher flow rate, lower cost of maintenance, and easier replacement are to to be solved.
In this study Taguchi method is used to find out the optimal designs of several components at the lowest cost improvement. We select three key components (valve, shock absorber, and structure frame) which are reported the most occurrence replacement for the present air pump. By using the finite element analysis software of ANSYS we simulate the strength analysis and find out their optimal designs.
The present results show the feasibility of combination of Taguchi method with the finite element analysis software of ANSYS to establish the best design of the air pump expert system (Expert System). It will provide useful information in the design industry to shorten the air pump product development time.
