| Abstract: | Two new types of ultrasonic transformers longitudinal cosine type and torsional similar cosine type are studied. The frequency equations and formulae for calculating the performance parameters and the dimensions of the horns are given. The resonant frequency and amplification of some simple horns of the new types and some complex horns composed by the new tapers and cylinder, or hyperbolic secant taper have been measured. The experimental results basically agreed with theoretical values. |
