In this paper, a new design of hybrid transducer consisting of individual longitudinal and torsional vibrators is investigated. Degeneracy approach for searching the same resonant frequency of both the longitudinal and torsional ceramic vibrators is the primary task of hybrid transducer design. In this study, a new structure is proposed so that a range of degeneracy can be found, which provides more possible configuration design of the longitudinal and torsional vibrators. A case study is presented to demonstrate the structure design and the approach of degeneracy. Also, an optimal design of large torque is achieved based on the searched range of degeneracy. With the determined driving frequency for both the longitudinal and torsional vibrators, simulation is carried out to verify the function and performance of the transducer.
