Computer Graphics and the Finite Element Method as Applied to Sonar Transducer Analysis.

摘要

In order to adequately understand the vibratory characteristics of electromechanical sonar transducers, two sophisticated techniques, the finite element method and state-of-the-art computer graphics, have been successfully combined. This process has for the first time vividly demonstrated the normal mode behavior of a Navy sonar transducer. This paper briefly describes the actual transducer being analyzed as well as the method used, gives results for the first three constant voltage drive resonant frequencies, and shows how computer graphics plays a key role in any such endeavor.
