Improvement of Structure and Procedure for Raising Acceptance Rate of Sonar Transducer

To raise the acceptance rate of sonar transducer in its development and production processes, an equivalent circuit model was built to analyze the factors influencing the acceptance rate. Consequently, a non-polarized piezoelectric ceramic was adopted in the structure of the transducer, and thermal transition of metallic material was applied to the procedure. A prototype of the sonar transducer with the improved structure and procedure was produced and tested. The results indicate that this improvement can raise the acceptance rate of the product.
