A new type of low-stress flexible hinge displacement amplifying mechanism

A new type of low-stress flexible hinge displacement is designed to effectively improve the load capacity of flexible hinge position transfer large mechanisms and voltage ceramic output displacement. The principle of differential leverage amplification and the method of two-way symmetrical cutting of the flexible hinge of the mechanism design the second-level leverage transfer transmission mechanism. The cutting of the flexible hinge part is conducive to reducing the concentration of partial stress of the flexible hinge, thereby reducing the overall as a whole. The stress is required for deformation. It derived the agglomeration of the organization and simulated the stiffness and displacement of the mechanism through the ANSYS finite element software. The simulation results show that the institution can effectively amplify the input displacement of voltage ceramic. After being cut, the exerting position of the same load output end is 11.614 & mu;m. Compared with the output end displacement of 0.00517 & mu;m without cutting, it has been significantly improved 2243.7%.
