Experimental Model of a Large Displacement Micro Tweezers Used for Force Display.

通过本课题的研究，取得了两个主要成果。(1)A找到了同时测量加载位置和加载力大小的方法。它使用H狭缝型双梁结构作为偏转机构。有限元仿真和实验模型验证了该方法的有效性。作为该发现的结果，我们可以知道操作者抓住镊子的任何部分的负载的实际大小。（2）对于具有力显示功能的微镊子来说，防止过载是重要的。针对外力作用下镊子可能出现的损坏现象，提出了一种新的防过载机构。

Through the research project, two main achievements are obtained.(1)A method for simultaneously measuring the loading position and the magnitude of the load force is found out. It uses an H-slit type double beam structure as the deflection mechanism. The effectiveness of the method is verified by FEA simulations and an experimental model. As a result of the finding, we can know the actual magnitude of the load whichever part of the tweezers is gripped by an operator.(2)Overload prevention is important for a micro tweezers with function of force display. Since unexpected external force may damage it. A new type of overload prevention mechanism is proposed for those tweezers with small deflection mechanism.
