| Abstract | A piezoelectric transducer using first bending vibration modes is proposed in this paper; it can be used as a stator for an ultrasonic motor. The transducer has a symmetrical structure, in which a conical horn is located at one end. On the tip of the horn, a cylindrical driving foot is machined. Bending vibrations are superimposed in the transducer to generate elliptical trajectory movement at the driving foot. The working principle of the proposed transducer is analyzed. The resonant frequencies and the electromechanical coupling factor of the bending modes are analyzed under different structural parameters. An improved structure for the initial model is proposed. The motion trajectory of the driving foot is obtained by transient analysis. The results can be a theoretical guidance for the design of piezoelectric actuator using bending transducer. |

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.
