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)提出了一种同时测量加载位置和加载力大小的方法。它采用H型狭缝式双梁结构作为偏转机构。通过有限元仿真和实验模型验证了该方法的有效性。这一发现的结果是，我们可以知道实际载荷的大小，无论操作人员抓住镊子的哪个部分。(2)对于具有力显示功能的微型镊子来说，防止超载是很重要的。因为意外的外力可能会损坏它。提出了一种新型的小挠度镊子防过载机构。

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.
