Design Optimization of Ultrasonic Transducer for Medical Application Based on an Integrating Methodertain part of the transducer, constrain functions are stresses of the stress-concentration zone. Optimization results showed that compared with the given initial parameters, the velocity of the optimum parameters was dramatically increased. Experiments were also performed and the results were in great agreement with the theoretical one.
