Abstract
A 2-D linear flexure stage system is designed with high structure stiffness using the laminar over-constrained weak-link mechanism presented in this paper. This design is a new development in the application of redundantly constrained laminar structures as weak-link mechanisms. The novelty of this new mechanical design is its fishbone-shaped multiple-parallelogram structure, which performs the function of a high-stiffness, high-precision linear motion guider with subcentimeter travel range and sub-nanometer positioning resolution. Potential applications of this new stage system include advanced development of ultra-precision positioning stages for the scanning x-ray nanoprobes, long-range scanning atomic force microscopes, and equipment for nanotechnology and semiconductor industries.
