摘要
The present invention relates to a method for phase optimization linked with a finite-element analysis program and a numerical value analysis program and a method for designing the phase optimization of an ultrasonic transducer by using the same. The present invention performs dynamic feature analysis and the modeling of an analyzed model in the finite-element analysis program and performs design variable update for phase optimization in the numerical value analysis program. Therefore, with the invention, phase optimization is possible even in a field in which the phase optimization is impossible due to a complex initial shape. In addition, the phase optimization is performed by using the numerical value analysis program so that a reasonable phase optimization result is obtained by applying various phase optimization algorithm to even a model with a physically impossible result.
