Abstract In order to clear up the burrs on soft magnetic ferrite without damaging the work-pieces, an ultrasonic horn was designed.Ultrasonic de-burring process was simplified into a particle spring forced vibration system composed of two springs with different stiffness coefficient.The minimum magnification of complex Gaussian horn was calculated after the failure condition was obtained.After calculating, the shape factor of complex Gaussian horn was proved 40% higher than the Exponent horn in the condition of minimum magnification, significantly decreased the stress concentration.The design process was verified by comparing the results of theoretical calculating with the finite element analyzing.
