| Abstract: | The mechanical and structural properties of the coniform horn of magnetostriction transducer are investigated in this paper. Geometric size based on actual resonance, magnifying coefficient of amplitude, distributing functions of the vibration speed and stress, as well as nodal section position are calculated, and natural frequency equation of the coniform horn of magnetostriction transducer is derived, which is applied to the design of magnetostriction transducer. |
