Abstract
To solve the problem of inadequate amplification ratio within the precision positioning platforms, a novel Z-shaped flexure hinge (ZFH) is proposed firstly in this paper. Meanwhile, a 2DOF XY precision positioning platform which realizes secondary amplification with bridge-shaped mechanisms and novel ZFHs is designed. The novel ZFH and the platform are analyzed by static modeling with compliance matrix method and the principle of force equilibrium. The simulation results show that the errors in both stiffness and amplification ratios of the platform are within 7%, and the performance of novel ZFH is improved by 50.70%. Finally, A prototype of the platform is fabricated for performance testing. The experimental results well validate the superior performance of the platform and novel ZFH.
期刊介绍：
Precision Engineering - Journal of the International Societies for Precision Engineering and Nanotechnology is devoted to the multidisciplinary study and practice of high accuracy engineering, metrology, and manufacturing. The journal takes an integrated approach to all subjects related to research, design, manufacture, performance validation, and application of high precision machines, instruments, and components, including fundamental and applied research and development in manufacturing processes, fabrication technology, and advanced measurement science. The scope includes precision-engineered systems and supporting metrology over the full range of length scales, from atom-based nanotechnology and advanced lithographic technology to large-scale systems, including optical and radio telescopes and macrometrology.
