摘要:
水声脉冲声管法可以测量水声材料的多个声学性能参数,如插入损失、反射系数等,而且还可以通过测得的复反射系数反演水声材料的纵波声速和衰减系数。通过复反射系数反演水声材料纵波声速和衰减系数时,因计算公式繁琐,工作过程耗时耗力、效率低下。针对该问题依据其计算原理开发了具有图形界面计算软件程序。该软件具有简单、易操作的界面,可根据测量数据快速的反演水声材料纵波声速和衰减系数。此外详细分析了测量误差对反演结果的影响,并通过实验测量成功地快速反演了浸水松木的纵波声速和衰减系数,当处理大量数据时满足了快速处理及直观显示的需求,同时体现了该软件的可靠性及高效性。
Abstract:
A number of parameters of the underwater acoustic material can be measured by pulse acoustic method, such as insertion loss and reflection coefficient, and the longitudinal wave velocity and attenuation coefficient of the underwater acoustic material can be retrieved according to the measured complex reflection coefficient. When the longitudinal wave velocity and attenuation coefficient of the underwater acoustic material were retrieved by the complex reflection coefficient, it is time-consuming and low-efficiency because the calculation process is complicated. According to the calculation principle of this problem, a program of graphic interface calculation software was developed. The software is simple and easy to operate, and the longitudinal wave velocity and attenuation coefficient of the underwater acoustic material can be retrieved according to the measured data quickly. The influence of measurement error on the inversion results was discussed in detail, and the longitudinal wave velocity and attenuation coefficient of soaking pine were retrieved quickly by carrying out experiment successfully, when dealing with a large number of data, the requirements of rapid processing and intuitive display were satisfied, and at the same time, the reliability and efficiency of the software were reflected.
