| Abstract: | Design of longitudinal composite ultrasonic transducer which is used in rotary ultrasonic machining is introduced. By theoretical analysis of ultrasonic transducer,it argues configuration feature,vibration equation,velocity field and stress field etc. in detail,and achieves magnifying coefficient of amplitude,displacement nodal position and maximum stress position. The modal analysis and harmonic solutions of finite element analyses of ultrasonic transducer are researched by using the finite element commerc... |
