Abstract

Sound field and radiation impedance are crucial acoustic performance parameters. Sound field calculation concerns sound propagation from a source and pertains to practical application problems within a specific environment. In contrast, radiation impedance is associated with the matching of the radiating elements with a circuit. Free boundary stepped radiators with high directional properties have significant application potential in the field of high-power gas medium ultrasonics. This study proposes a simulation for the computational estimation of the radiation field and impedance of stepped radiators based on the Rayleigh method. The axial sound pressure and directivity of the rectangular stepped radiator are calculated theoretically. At the same time, the radiation impedance is calculated. The results of the sound field test and radiation impedance calculations verified the validity of the proposed method. Thus, a practical and efficient approach to the analysis of the acoustic performance of arbitrary sound radiator was realized. The proposed method offers valuable insights and addresses a crucial gap in understanding these parameters for diverse radiator configurations.

阶梯式超声辐射器的研究

声场和辐射阻抗是重要的声学性能参数。声场计算涉及声源的声音传播，涉及特定环境下的实际应用问题。相反，辐射阻抗与辐射元件与电路的匹配有关。具有高定向性能的自由边界阶梯式辐射体在大功率气介质超声领域具有重要的应用潜力。本文提出了一种基于瑞利法的阶梯辐射器辐射场和阻抗计算估计的仿真方法。对矩形阶梯辐射器的轴向声压和指向性进行了理论计算。同时，计算了辐射阻抗。声场测试和辐射阻抗计算结果验证了该方法的有效性。从而实现了一种实用、高效的分析任意声辐射体声学性能的方法。所提出的方法提供了有价值的见解，并解决了理解不同散热器配置的这些参数的关键差距。
