Ultrasonic array optimization arrangement method for improving acoustic radiation force

The invention discloses an ultrasonic array optimization arrangement method for improving acoustic radiation force, and relates to the technical field of ultrasonic suspension, and the method comprises the steps: determining the array curvature and the working range of an ultrasonic suspension device; sequentially determining the pitch angle range of each circular ring from the center of the concave spherical surface to the outside according to the array curvature; determining the number of transducers contained in each circular ring and the pitch angle of the transducer according to an equivalent area method; and optimizing the space directional angle of each circular ring transducer. According to the method, the acoustic radiation force provided by the ultrasonic suspension array of the commercial transducer can be greatly improved, the problem that the suspension capacity is insufficient due to the fact that the sound pressure amplitude of a common commercial transducer is small is solved, the energy effic
