Design and Experimental Investigation of XY Compliant Mechanism for Precision Applications

Abstract

A XY compliant mechanism is designed for the precision application with higher range, precision, and accuracy. In earlier work, many researchers have used different methods to design compliant mechanism. In this paper, XY positioning stage is designed using blocks method. However, the model is monolithic in nature to avoid joints. By using wire EDM, the XY model is manufactured. Voice coil actuators are used for the displacement, which give larger range. Analytical modeling is carried out and is validated with MATLAB results. Finally, experimentation is done for performance analysis. The XY model gives ±6mm with motion direction. The XY model evaluates both static and dynamic performances.
