新型撓性平移接頭之最佳化設計

Design Optimization of A Compliant Translational Joint

指導教授 : 李志中

摘要


本文內容為研究撓性平移接頭之設計。首先從現有期刊及專利等文獻了解各類型撓性平移接頭的優缺點,以此整理出一個正確的設計方向,接著運用材料力學相關理論、參考文獻中的延伸公式以及有限元素法來分析接頭的各項性能指數,包括運動範圍、軸偏位、勁度比、應力集中、線性特徵、耦合性,並以此提出新式接頭之設計。為了提升接頭精度,使用ANSYS之最佳化模組進行結構最佳化,然後藉由實驗,量測出新式接頭的各項性能指數來驗證模擬結果。最後根據模擬以及實驗的結果,可知新式接頭的各項性能指數確實都比過去的文獻優越許多。

並列摘要


This thesis studies the design of compliant translational joint (CT joint). First, to realize the pros and cons of various CT joints, a literature survey for the CT joint is conducted. Principles of design are established by the results of literature review. Then, factors that affect the benchmarking indexes are investigated by finite element analysis, equations adapted from the literature and mechanics of materials. An innovative design of the CT joint is then proposed. To enhance the range of motion and improve precision, structural optimization is performed via CAE’s optimization module. Finally, experiments on the rigidity are conducted and results are compared to the results of finite element analysis. According to the results of simulation and experiment, it is concluded that the benchmarking indexes of new design are much better than any other CT joints.
