Abstract	In this paper, each parameter affecting the performance of spherical ultrasonic transducer is simulated by a reasonable finite element model (FEM), and optimal design parameters are obtained for a 50MHz spherical ultrasonic transducer. Simulation results show that the ceramic thickness of spherical ultrasonic transducer is calculated to be 40.9um and the center frequency is 50MHz; The radius for spherical aperture is 550um and the vibration mode is single; The acoustic performance is greatly impacted by the radius of spherical curvature, so the best radius of spherical curvature should be less than the radius of ceramic aperture, and the focal spot of the acoustic field and the sensitivity of the transducer can be improved; Adding an acoustic matching layer can improve the transmission capacity and the sound field focused energy, and the best matching layer thickness is approximately 13.5um.
