| Abstract | The proposed paper addresses the problem of vibration-to-electric energy conversion using giant magnetostrictive material — TERFENOL-D. Both theoretical and experimental results of the study of performance of magnetostrictive transducer which was built at Chalmers University of Technology are presented. The mathematical models have been developed for modeling of magnetostrictive transducer based on constitutive equations of magnetoelastic behavior of TERFENOL-D rod and standard formulae of electromagnetism for induced voltage and current in the pick-up coil due to variation of magnetic field. The developed models are used to evaluate induced voltage and electrical power output for displacement driven and as well as force driven transducers. Several experiments using test rig generating periodic excitations with frequency up to 1000 Hz have been conducted for newly developed physical prototype of transducer having TERFENOL-D rod with 50 mm in length and 15 mm in diameter as active material. The validity of the transducer model is illustrated by comparison simulation data with experiment. The obtained results of the study the vibration-to-electric energy conversion using TERFENOL-D have confirmed the potential of using giant magnetostrictive materials for power harvesting from vibration. |

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.
