摘　　要：为了寻求最佳性能的Unimorph换能器,本文根据简支边界下薄圆片弯曲换能器的共振频率方程,计算和分析了这种换能器的共振频率、有效机电耦合系数与换能器尺寸之间的关系,得出了设计换能器的最佳几何参数。结论对实际设计有一定指导意义。To find the optimal performance Unimorph transducer, based on the resonance frequency equation of thin disk flexural transducer with a simply supported boundary, the relations between the resonance frequency, the effective electromechanical coupling coefficient and size of the transducer have been calculated and analyzed, the optimum design of geometric parameters has been obtained. The conclusions has the certain instruction significance to the actual design.
