中文摘要:
      矢量传感器在水声技术领域广泛的应用。它通常工作在自由场中,不受边界条件的影响,但实际应用中具有复杂形状的障板对传感器性能有很大影响。利用边界元方法,在不规则障板边界条件下,对矢量传感器的散射声场进行了计算,得出了传感器的指向性图。在水池中对不同边界条件下矢量传感器的指向性进行了测试,将数值计算与实测结果进行比对,验证了计算方法,并给出了研究结论。
英文摘要:
      Vector sensors have a number of advantages over traditional hydrophone arrays.It is usually assumed that sensors are located in a free space,however problems arise when considering the presence of boundaries,especially complicated reflecting boundaries.This paper proposes a gen-eral model of sound scattering and directivity pattern for a vector sensor located on a complicated reflecting boundary.Numerical analyses and calculation are carried out with ANSYS and SYSNO-ISE.The calculated results are in agreement with directivity patterns measured in a water tank.
