An Alternative Method to Optimize Octagonal-Ring Transducer

Abstract:

Nowadays there is no precision theory to determine the parameters of an octagonal ring type transducer with high sensitivity and adequate stability according to its load condition. Stress design criterion and a method to optimize octagonal ring based on finite element method (FEM) are proposed. Full-load stress distributions in P and F directions of 3 octagonal-ring transducers are studied by FEM, and the stress prediction precision of FEM is validated by experimental calibration. Experiment results suggest that the FEM predicted max stress is less than the stress design criterion both in P direction and in F direction. The average relative errors are all less than 20%. With fully loaded stress distributions of octagonal-ring sensor, results from FEM are of contribution to optimize transducer structure. Compared with conventional experimental method, analysis based on FEM is efficient and intuitionistic, and can supply theoretical guidance to design a transducer.
