Abstract
The paper proposes a model and analysis of spherical-cymbal piezoelectric transducer. First, we select materials for force-sensitive element, the metal end cap and ring and epoxy resin. The load transfer law of the spherical-cymbal piezoelectric transducer is analyzed. Then, resonant frequency test, axial vibration displacement test and ultimate static pressure test are implemented in experiment. The experimental results show that the spherical-cymbal piezoelectric transducer outperforms the traditional cymbal piezoelectric transducer. The <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">P <sub>max</sub></i> value can increase up to 10% under different geometric parameters. This paper is conducted to provide new insight into the design of cymbal piezoelectric transducer.
