中文摘要 | 一種低轉速高扭矩之垂直軸型複材風力機葉輪,具有薩瓦尼(Savonius)轉子系統之製程及性能測試被呈現。其中改良型薩瓦尼轉子系統是由S型葉片組件及圓型端板葉片組件所組成,而S型葉片組件是由兩個半桶型組成,剛好設定夾於上下圓型端板之間且互相重疊於圓中心距,使整體轉子系統繞著中心垂直軸旋轉產生風洞效應。而一種真空樹脂轉注成型法及模壓成型法各被應用於該複材葉片及端板預成形物組件,其中預成形物更包括S型玻璃纖維布、圓型玻璃纖維布、圓型瓦楞板芯材及金屬軸桿等嵌入物所組成三明治結構體。藉由以上預成形物組合,再利用真空樹脂轉注成型(VA-RTM)法將半桶型葉片組件抽真空灌注樹脂並熱硬化成形,同時也藉由模壓成型法利用瓦楞板芯材之彈性性質與玻璃纖維布、樹脂予以擠壓熱硬化一體成形。其中嵌入物結構包括具有中心金屬軸桿及圓型瓦楞板芯材等設計為具有補強鎖固、一體成形功能。在這研究中也利用膠合製程技術將各單階葉片組件膠合成多階式複材風力機葉輪轉子系統。在理論分析及量測方面,利用有限單元分析軟體ANSYS來分析複材葉輪結構應力分佈及搭配一個300W三相交流無刷發電機、塔架與風洞實驗設備來量測其轉速、功率等以驗證及預測說明阻力型垂直風力機葉輪結構體及發電之功能性、完整性。 |
英文摘要 | The testing and manufacturing of a composite vertical axis wind turbine (VAWT) with modified Savonius rotor system are presented. Modified Savonius rotor system made out of the S-shaped blades between two circular end plates is a very simple concept where the whole rotor turns around a vertical axis. A vacuum assisted resin transfer molding (VARTM) technique was used to fabricate composite blade and end plate by stacking pieces of glass-fiber fabrics and polypropylene corrugated core in a vacuum pressure mold. In VARTM, resin is injected into a rigid mold filled with fiber preform and subsequent curing. These preforms include the circular polypropylene corrugated core and S-shaped glass fabric structures. This research also be used to develop adhesive bonding technique for multi-stage components in composite vertical axis wind turbine rotor. The cured parts were subjected to static test to validate the reliability of the composite rotor. The composite rotor was used to fabricate a 300 W wind power system for long terms endurance and efficiency testing. A number of composite VAWT rotors were fabricated to demonstrate the feasibility and applications of the proposed testing and manufacturing methods. |
