ABSTRACT: Anultrasonic compound horn
is designed and manufactured, and the horn is analyzed by wave equation, finite
element method and test. The modal frequencies and frequencies of the first and
second longitudinal vibration of the horn are obtained by the finite element
analysis. The horn is made and modal testing is carried out. The modal
frequencies of the first and second longitudinal vibration are obtained
respectively. The test results are in good agreement with the theoretical
calculation. Experimental results show the maximum amplitude of the horn can
reach 9nm with applied excitation voltage of amplitude 7V and frequency 21,450Hz, when the amplitude of
voltage increasesto 80V, the horn of maximum amplitude reaches23 μm. The maximum amplitude of the horn is approximately
proportional to the amplitude of excitation voltage. The horn has the
characteristics of high sensitivity and large amplitude, and can be used in
ultrasonic machining and other fields.
