On the influence of the flexure hinge orientation in planar compliant mechanisms for ultra-precision applications

This paper presents the investigation of specific geometric parameters of planar compliant mechanisms with flexure hinges. The main focus is on the geometrical orientation of the flexure hinges and the form of the link connections between them. The synthesis of the compliant mechanism using a selected rigid-body model by replacing the hinges and the design process of the mechanism are shown. Therefore different parameters are selected and FEM simulations are done to investigate the motion behaviour. After the simulation process a special test bench is designed to measure the path of motion of prototypes and to verify the simulation results.
