The fre-quency equations are derived according to stress match, consid-ering gear as a thin bar and adopting exponential horn. Then the influences of vibration of transformer which consists of horn and gear are explored, which come from the length of horn and the machining frequency. It has been discovered that the reso-nance frequency of the horn is the detune one of transformer and the resonance frequency is not same as one of horn, which provide theoretical rules for transformer design.

鉴于此，根据应力耦合，将齿轮作为圆盘，采用指数型变幅杆，推导频率方程，对变幅杆的设计长度和变幅器振动频率进行数值分析，发现变幅杆的共振频率恰好是变幅器的失谐频率，变幅器的共振频率与变幅杆的固有频率也不相同，这能够为超声珩齿变幅器的设计提供理论依据。
