Additive Manufacturing of Titanium Alloys: State of the Art, Challenges and Opportunities

為了解決PBF的問題，作者Dutta, Bhaskar/ Froes, Francis H 這樣論述：

Additive Manufacturing of Titanium Alloys: State of the Art, Challenges and Opportunities provides alternative methods to the conventional approach for the fabrication of the majority of titanium components produced via the cast and wrought technique, a process which involves a considerable amount o

f expensive machining.In contrast, the Additive Manufacturing (AM) approach allows very close to final part configuration to be directly fabricated minimizing machining cost, while achieving mechanical properties at least at cast and wrought levels. In addition, the book offers the benefit of signif

icant savings through better material utilization for parts with high buy-to-fly ratios (ratio of initial stock mass to final part mass before and after manufacturing). As titanium additive manufacturing has attracted considerable attention from both academicians and technologists, and has already l

ed to many applications in aerospace and terrestrial systems, as well as in the medical industry, this book explores the unique shape making capabilities and attractive mechanical properties which make titanium an ideal material for the additive manufacturing industry. Includes coverage of the funda

mentals of microstructural evolution in titanium alloysIntroduces readers to the various Additive Manufacturing Technologies, such as Powder Bed Fusion (PBF) and Directed Energy Deposition (DED)Looks at the future of Titanium Additive ManufacturingProvides a complete review of the science, technolog

y, and applications of Titanium Additive Manufacturing (AM)

改良型無刷直流馬達無感測驅動器研製

為了解決PBF的問題，作者陳仕軒 這樣論述：

本論文主要是研製一改良型無刷直流馬達無感測驅動器，本驅動器主要應用在車用無刷直流馬達風扇控制，輸入電壓範圍是10伏特~20伏特。本實驗控制核心是瑞薩電子公司RL78/F14數位訊號處理器R5F10PGG，用來實現無感測之馬達定位、啟動、驅動及保護等功能。為使無感測驅動器能達到可靠的啟動，在馬達開迴路啟動前藉判斷輸入電壓，給予所需的啟動參數。由實驗結果發現，模擬的霍爾訊號與原始霍爾訊號有角度誤差，因此使用軟體程式對落後訊號做相位超前補償。為使驅動波形在轉態時更加穩定，在相位未超前驅動波形轉態為相位超前驅動波形時，加入磁滯轉態銜接策略。最後針對馬達在驅動時若受到擾動，在軟體中設計保護判斷，經實驗

驗證能有效防止擾動造成的故障。
