摘要

本文主要放在微挾持器的設計上，利用撓性機構可儲能的特性,發展雙穩態的機構，設計出具雙穩態特性的微挾持器，使用PSEUDO RIGID BODY MODEL進行撓性機構的設計，設計過程使用虛功原理,能量法來進行雙穩態性質分析，推出受力與微挾持輸出力道的關係式，最後設計推動挾持器所需的致動器，而致動器的設計需符合微挾持器的需求，完成微夾持器整體挾持機構的設計。

The major of this thesis is the design of microgripper, and developing bistable mechanism utilizing properties of energy storage of compliant hinges, to design the microgripper which has bistable properties. PSEUDO RIGID BODY MODEL was used in the design of the compliant mechanism. The design process used the principle of virtual work and energy method to do the analysis of bistable properties, and derived the related expression between the input force and the output force of the microgripper. Finally it designed an actuator which was needed to push the gripper, and the design of actuator conformed to the requirement to microgripper and completed the design for all microgripper mechanism.
