Abstract | A novel tracked travelling system driven by a Langevin piezoelectric transducer is proposed. It has advantages of large driving force, high mechanical integration, well reliability, requiring no lubrication, and having the potential application in planetary exploration. The tracked travelling system comprises of an actuating mechanism and a track. The actuating mechanism includes a Langevin piezoelectric transducer and two annular parts symmetrically placed at two ends of the transducer. The track is pressed in contact to the outer surfaces of the annular parts. Traveling rotating waves are generated in two annular parts, and then the microscopic elliptical motions at the outer surface of the annular parts will be generated to drive the track to move by friction force. The actuating mechanism is analyzed by using FEM, and the simulation results are compared with the vibration measurements results. And then the prototype of the tracked travelling system was assembled and investigated experimentally for its performance. The maximum average velocities to bi-directional movements were 72mm/s and 61.5mm/s under the excitation voltage of 500Vpp and frequency of 35.1 kHz, respectively. |

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.
