Design and Simulation of Micro-Displacement Magnification Mechanism Based on Flexible Hinges

Abstract:

A kind of triple micro-displacement magnification mechanism was designed according to the magnification principle of lever. Introduced the magnifying principle of the mechanism, analyzed the magnify ability and the relation between magnification times and exterior load, deduced the calculational equation of precise magnification times pass the analyes of stress, and used the Abqus to carry on finite element simulation. The result of simulation indicates that there existed certain difference between the value of theoretical computation and finite element simulation, the value of finite element simulation is less than theoretical computation, and the D-value enlarges along with the enlarge of exterior load. There are linear relationgship between magnification times and exterior load.
