Significance Tests on Design Factors Affecting the Frequency Performance of Spherical Cymbal Transducer

Abstract

Orthogonal experiment was used to optimize the design of spherical cymbal transducer. Through variance analysis of orthogonal experiment results, the primary and secondary order that each design factor affects the frequency performance of spherical cymbal transducer has been found. At the same time, the significant level of each design factor has been gained. Those factors which have highly significant or significant effects on the frequency performance of spherical cymbal transducer should be considered carefully during design spherical cymbal transducer, and those factors which have no significant effects can be ignored. In this way, the design factors were reduced, and the design complexity of spherical cymbal transducer was simplified.

Structural Design and Physical Mechanism of Axial and Radial Sandwich Resonators with Piezoelectric Ceramics: A Review

“…He also used a piezoelectric transducer array in the underwater large target test [120]. Wu [121][122][123][124][125] also proposed the spherical crown intelligent structure shown in Figure 25. Research involving this structure revealed that the spherical end cap can improve the output efficiency and that the design can be applied at increased water depths.…”

“…The experimental results show that when the diameter of the spherical pressure hydrophone is 36 mm, the operating frequency is 50 Hz-10 kHz, the low frequency receiving sensitivity is −198.4 dB (0 dB = 1 V/Pa) and the equivalent self-noise spectrum level is 46.5 dB@1 kHz. This designed structure can work Wu [121][122][123][124][125] also proposed the spherical crown intelligent structure shown in Figure 25. Research involving this structure revealed that the spherical end cap can improve the output efficiency and that the design can be applied at increased water depths.…”
