In this paper, the effect of cross-section area ratio between the two ends of a step-bar ultrasonic transformer on its resonance frequency is studied. Experiments were carried out on two groups of transformers, one with equal length of the two parts and the other with unequal lengths. A relation between the resonance-frequency variation of the transformer, β , and logarithm of the cross-section areas, ln N ~(2), has been found. Characteristics of the variation with respect to the order of vibration are analyzed. The result is useful to the research and design of transformers.
