The paper considers the issues of calculating the acoustic dimensions of ultrasonic stepwise composite transformers of oscillatory velocity with a developed radiation surface. The analysis of the effect on the transformation ratio of the features of oscillations of a flat developed disk surface radiation is presented. It is shown that the geometrical dimensions of the disk surface of radiation set a certain mode of surface oscillations and are associated with the requirements of specific technological processes. This requires an adjustment of the calculated value of the transformation ratio and the acoustic dimensions of the step of a smaller diameter of the composite speed transformer in order to preserve the resonant frequency. It is shown that with transformation ratios of more than 4, the one-dimensional computational model gives a significant error, since does not take into account bending vibrations of the disk surface radiation.References
