Research on the Effects of Geometrical Errors of Tangential Ring Acoustic Transducer Based on FEM Model
2025
Overview
The Tangential ring acoustic transducer is one of the most concerned transducers for its advantages in production and performance. In this paper, we established a properly partitioned and finely meshed FEM model to illustrate the effects of tiny scale geometrical errors. The FEM discretization error is suppressed by the finely built mesh, allowing a precise analysis on the small impacts of radical random and elliptical geometrical errors on the tangential ring transducer. Conclusions could be made that the errors contribute little to the acoustic performance including transmitting voltage response (TVR) and directionality, however; the stressed zone is enlarged obviously by both kinds of geometrical errors due to stress concentration, which may affect the strength and maximum power available of the transducer.
