摘要

声学全息术及其在工程中的实际应用始于20世纪末。目前，这种技术通常用于定位声源。本文介绍了在米格-29稳定器全尺寸疲劳试验中使用声学摄像机定位声源的方法。在疲劳测试过程中，被测试的结构会发出一系列故障、吱吱声或跳动的声音。这些声音是承受动态载荷的结构的典型声音，但它们也可以作为疲劳失效部位的诊断信息来源。本文介绍了疲劳试验过程中的测量结果。由于对测量结果的分析，有可能识别出声音的基本来源。

Localization of Sound Sources during Full Scale Fatigue Test of the Vertical Stabilizer with the Acoustic Holography Technique

Abstract An acoustic holography and its practical applications in engineering began to develop at the end of the 20th century. Currently, this technique is being commonly used to locate sound sources. This paper presents the use of an acoustic camera to locate sound sources during the Full Scale Fatigue Test of the MiG-29 stabilizer. During fatigue tests, the tested structure issues a series of sounds in the form of glitches, creaks or beats. These sounds are typical for a structure subjected to dynamic loading, but they can also be a source of diagnostic information about places of fatigue failures. The paper presents the results of measurements made during the fatigue test. Thanks to the analysis of the measurement results, it was possible to identify areas that are the basic source of sounds.
