An Optimal Process for Ultrasonic Amplitude Transformer Design with FEM

The amplitude transformer is one of the most important parts in ultrasonic work system. To amplitude transformer, the resonant frequency and location of flange are two crucial design objectives. For variable cross-section amplitude transformer design, the traditional theory calculation seems to be too verbose and sometime hard to get efficient solution. This paper focuses on using commercial FEM software-ANSYS to achieve an optimal design of amplitude transformer.
