Theoretical Analysis of Levers in a Precision Stage for Large Displacement

정밀 스테이지에서 출력변위 확대를 위한 레버의 해석

Lever mechanisms are usually employed to enlarge output displacement in precision stages. In this study, theoretical analysis of a lever is presented including bending effect and relation between dimension parameters and an objective function. The objective function is chosen as multiplication of magnification ratio and forcedisplacement transmission. Through theoretical analysis, this study presents optimal values for the parameters and the analysis is verified by finite element method.
