Research on Lamina Emergent Mechanisms

Abstract

The research and development, basic principles, analysis and design methods of the Lamina Emergent Mechanisms are reviewed. As a compliant mechanism, Lamina Emergent Mechanisms (LEM) is a kind of device which is manufactured by a monolithic machine device and belongs to a non-hinge mechanism. Their motion is obtained through elastic deformation of compliant members which can avoid the vibration shock, friction, wear, lubrication and other defects. The analysis methods are described and the influence factors that affect compliance are also analyzed. The compliant mechanisms are likely to be widely applied in micromechanical systems and nanomechanical systems.
