| Abstract | Bridge-type micro-displacement mechanism based on flexible hinge is a classical displacement magnifying mechanism. A flexible branched chain model was established to analyze the characteristics of the mechanism according to its symmetrical structure, thus the formulas for calculating output displacement and displacement amplification ratio of the displacement amplification mechanism were derived. Finite element simulation was carried on by software ANSYS11.0, and then compared with the theoretical model. Finally, an experiment sample piece was designed and processed to verify the theoretical model. The results showed that: the displacement amplification ratio of the bridge-type micro-displacement mechanism will increase first and then decrease, while the distance of the flexible hinges ly increase, and when the influence angle of amplification ratio α = 0.688°, the displacement amplification ratio get its maximum; Bridge-type micro-displacement mechanism can realize a displacement amplification ratio of more than 40 times, but the error will be amplified at the same time, so the amplification ratio of the bridge-type amplification mechanism should not be too large. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
