使用 ANSYS(R) 有限元软件研究了材料特性和尺寸变化对铙钹换能器基本谐振频率的影响。计算空气和水负载的振动模式形状、共振频率和导纳谱。在高达 200 kHz 的频率范围内，建模的导纳谱与实验测量的导纳谱之间观察到非常一致，从而证明了模型的有效性。计算表明，通过改变钹帽材料或尺寸可以轻松操纵基本谐振频率。
The effect of material properties and dimensional changes on the fundamental resonance frequency of the cymbal transducer has been investigated using the ANSYS(R) finite element software. Vibration mode shapes, resonance frequencies, and admittance spectra for both air- and water-loading are calculated. Very good agreement is observed between the modeled and experimentally measured admittance spectra in the frequency range up to 200 kHz, establishing the validity of the model. The calculations show that the fundamental resonance frequency can be manipulated easily by changing the cymbal cap material or dimensions.
