Design of a horn for high amplitude of longitudinal vibration
A design of an equal stress ultrasonic horn for high amplitude is presented. Based on the longitudinal vibration theory, ANSYS modal and harmonic response analysis, an equal stress horn of required frequency is obtained. The dynamic characteristics of four kinds of typical horns are also simulated and compared to verify the accuracy of the design. The designed horn is then manufactured and tested, the results show that a peak-to-peak vibration amplitude reached 148 um at the driving voltage of 198Vp-p.
