摘要
从界面反射系数与界面两侧介质声阻抗的基本关系出发,研究了声波在固/液界面多次反射回波衰减规律与液体特性声阻抗间的关系。本文以铝板作为超声反射基板,用室温的自来水作为标准液体,以超声波在铝/水界面的多次反射回波作为参照,对检测试验系统进行参数标定,再将声波在铝/硅油界面的多次反射回波与其进行比对,通过分析多次回波衰减测得声波在铝/硅油界面的反射率,进而获得密闭容器内硅油的特性声阻抗。结果表明,基于界面多次衰减规律可实现密闭容器内液体介质特性阻抗非介入测试,为以超声为基础的高压电缆终端瓷套内油位或油品检测与评价奠定了基础。
In the light of the basic relationship between the reflection coefficient of the interface and acoustic impedance interface on both sides of the media, the relationship between multiple acoustic echo attenuation in the solid-liquid interface regularity and characteristic acoustic impedance between the liquid is studied. In this paper, aluminum plate as ultrasound reflective substrate, with room temperature tap water as a standard liquid, in a number of ultrasonic echoes the aluminum-water interface as a reference for testing the system parameter calibration, the acoustic wave in the aluminum-silicone oil interface was compared with the multiple reflection echo, analysis of several acoustic echo attenuation measured reflectance aluminum-silicone interface, obtaining an airtight container characteristic acoustic impedance by silicone oil. The results showed that the attenuation of multiple-based interface can be achieved in a sealed container liquid medium characteristic impedance of the non-invasive test, based on ultrasound for high voltage cable terminal porcelain sleeve oil level detection or evaluation lays the foundation.
