    Abstract: 熱致動型的微型撓性夾持器可由於施於彈性結構體溫度變化值,藉熱變形使得一體成型的撓性結構達到機構作動效果,實現熱致動的微型夾持功能。 本文參考力致動型的微型撓性夾持器的設計領域、邊界條件及設計要求,以考慮熱變形的拓樸最佳化重新設計。 研究中使用材料分佈法的拓樸最佳化設計策略,滿足邊界條件及受限總材料使用量下,最大化輸出位移的性能。 針對拓樸形態圖中所出現的撓性接頭現象,本文以形狀最佳化設計方法來改善拓樸形態圖中的撓性接頭現象,同時將拓樸最佳化後的設計外形加以改善,使拓樸形態圖能成為明確可應用的工程設計圖,完成熱致動式撓性夾持器的拓樸與形狀最佳化設計。
    This paper develops a topology optimization approach including the thermal effect to actuate a one-piece micro-gripper compliant mechanism. To deal with the reasonable and applicable flexural joints created after topology optimization, a shape optimization has been generated to further improve the dimensions of the flexural joints as well as the whole performance of the one-peace micro-mechanism. The concepts and key points of the presented approach are given in the paper and verified by an existing engineering case.
