Abstract

A displacement amplifier based on the bridge-lever-type hinge mechanisms is developed and optimized in this paper. The proposed design not only maintains a compact and symmetrical structure, but also features a high amplification ratio. To reduce the displacement loss and enhance the load capacity of the amplifier, the hybrid flexure hinges are employed in the novel design. The analyzed models for the amplification ratio and resonance frequency calculation are established based on the matrix method and Lagrangian method respectively, which are verified by finite-element analysis (FEA) and displacement experiment. Based on the established model, an optimization via the NSGA- Ⅱ algorithm is performed to estimate the performance of the hinge mechanism.
