撓性旋轉接頭之最佳化設計

Abstract

本文內容為研究撓性旋轉接頭之設計。首先從現有期刊及專利等文獻了解各類型撓性旋轉接頭的優缺點，以此歸納出正確的設計方向，接著使用有限元素分析以及材料力學相關理論來分析接頭的各項性能指數，包括運動範圍、軸偏位、勁度比、應力集中與成型性，並以此提出新式接頭之設計。爲了提升接頭運動範圍與精準度，使用ANSYS之最佳化模組進行結構最佳化設計，最後藉由實驗，量測出新式接頭的各項性能指數來驗證模擬的結果，而根據模擬以及實驗的結果，新式接頭的各項性能指數確實都比過去文獻優越許多。

This thesis studies the design of compliant revolute joint (CR joint). First, to realize the pros and cons of various CR joints, a literature survey for the CR joint is conducted. The design directions are established by the results of literature review. Then, factors that affect the benchmarking indexes are investigated by finite element analysis and mechanics of materials. An innovative design of the CR 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 CR joints.
