中文摘要:
      文章研究了拥有喇叭型前辐射头的纵振Tonpilz型压电水声换能器的参数优化问题。希望可以通过合理的调整Tonpilz型换能器各部分的几何参数,得到满意的频带宽度。研究结果表明,在没有采用其它频带展宽方法的前提下,通过优化几何参数,可以降低换能器的机械品质因素Qm,从而增大带宽。
英文摘要:
      This paper discusses the geometric parameter optimization of longitudinal Tonpilz underwater acoustic transducers. It is hoped that a satisfactory bandwidth can be obtained by adjusting its geometric parameters. The research shows that, without taking any additional measures for bandwidth expansion, the value of mechanical quality factor Qm can be lowered and their bandwidth by geometric parameter optimization alone.
