英文摘要：

The resonant frequency equation and the special output terminal displacement amplitude of the two dimensional vibration direction convertor are studied by coupled vibration theory, model analysis and experimental measurement. The results show that the measured frequency agrees with the calculated frequency. Moreover, the experimental and model analysises also show that the energy gathering function of the two dimensional vibration direction convertor is very good.
