Design Optimization of Ultrasonic Transducer for Medical Application Based on an Integrating Method
Abstract
Ultrasonic Transducer are widely used in manufacture and medical surgery. A new method to optimize ultrasonic transducer for medical application is introduced, which is characterized by integrating Analytical Method, Finite Element Method and Constrained Variable Method. In our optimization process, the optimization aim is output power of the transducer, which is the most important parameter to value the performance of a transducer and could be achieved by the product of impact force at the tip of the ultrasonic transducer and vibration velocity amplitudes. Design variables are dimensions of certain 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.
