Abstract

As nano/micro devices become smaller, it is important to manipulate them with highly accurate control. The design of micro-joints is important for highly accurate movement. An elastic joint, one of type of micro-joint that is commonly used for rotational movement, however, has a limitation in terms of its small rotational range. This paper discusses a new micro-joint based on an elastic design concept for large rotational movement. The proposed micro-joint was designed with a simple shape of two thin plates. For large rotational movement with small force, a modified micro-joint with a helical structure was proposed. Through numerical simulation, the proposed micro-joint is estimated to have a large rotation that can be obtained with only a small force.
基于弹性设计理念的大旋转运动高柔性微关节
随着纳米/微器件的小型化,对其进行高精度控制变得尤为重要。微关节的设计是实现高精度运动的关键。弹性关节是一种常用的用于旋转运动的微关节,但其旋转范围小,存在一定的局限性。本文讨论了一种基于弹性设计思想的大型旋转运动微关节。所提出的微关节被设计成两个薄板的简单形状。针对大的旋转运动和小的作用力,提出了一种改进的螺旋结构微关节。通过数值模拟,估计所提出的微关节仅用较小的力即可获得较大的旋转。
