| 复合棒换能器通常采用多模态耦合方法实现宽带性能。增材制造技术可以解决采用粘接制作的传统纵弯耦合空腔前盖板接缝刚度不足的问题。该文为改善复合棒换能器带宽性能，基于金属增材制造加工方式，采用拓扑优化设计空腔结构，初步扩展了换能器的带宽。接下来，使用遗传算法进一步优化空腔尺寸，实现更好的带宽性能，仿真计算得到优化后换能器带宽达到55.3 kHz(带内起伏±3 dB)，相比优化前带宽扩展了82%。仿真与实验结果均表明采用遗传算法优化的换能器前盖板在增加换能器带宽方面具有显著效果。 |
| 英文摘要: |
| Tonpliz transducers typically use a multimodal coupling approach to achieve broadband performance, and additive manufacturing can solve the problem of insufficient stiffness in the seams of traditional cavity front cover plates made by bonding. In order to improve the bandwidth performance of the Tonpliz transducer, based on the metal additive manufacturing processing method, the cavity structure is designed by topology optimization, and the bandwidth of the transducer is preliminarily expanded. Next, the genetic algorithm is used to further optimize the cavity size to achieve better bandwidth performance, and the simulation results show that the optimized transducer bandwidth reaches 55.3 kHz (in-band fluctuation ±3 dB), which is 82% longer than that before optimization. Simulation and experimental results show that the front cover of the transducer optimized by genetic algorithm has a significant effect in increasing the bandwidth of the transducer. |
