| Abstract | Ultrasonic transducer is the kernel part of ultrasonic vibration system, changes electric energy into mechanical energy and determines the performance of system mostly. To reduce the temperature of ultrasonic surgery scalpel, it is necessary to analyze the energy loss of the ultrasonic transducer. First, The energy loss model of the thin equation section rod is deduced based on the theory of electrical transmission line and two ports network, while taking none but internal friction into account. Then, the energy loss model of the longitudinal direction ultrasonic transducer is established based on the theory of electrical transmission line and Mason model. The difference of maxim import conductance between the theory calculated value and experiment value is 0.065 S in the experiment. The main reason is taking no structure loss of transducer into accounted. Compared with the traditional plural constant model, this method can easily calculate the energy loss of the ultrasonic transducer as long as the material mechanical quality factor is given. |

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.
