Abstract:As a new type of mechanism, which characterizes that all kinematic pairs are designed as flexure hinges to play the same role as conventional joints, and may achieve a very high positioning accuracy as well as to decrease the manufacturing and assembly costs, the fully compliant mechanism provides a perfect alternative for the design of the motion amplification mechanism in actuation systems for micromanipulation applications. In this paper, the design issues on the fully motion amplifier are systematically discussed: based on the enumeration for the typical structures of the fully compliant motion amplification mechanisms and comprehensive considerations for their structural design, several novel high-accuracy and large-stroke mechanisms for amplifying the motion have been developed.
Keywords:fully compliant mechanism  nanometer range resolution  flexure hinge  motion amplification
