摘要

摘要本文讨论了某型滑翔机绝缘梁结构的疲劳试验结果。试验结果用于评估应变测量法诊断梁损伤的潜力，该方法涉及梁销中一个金属配件的解开。变形测量方法在复合材料结构诊断过程中的有效性得到了证实，同时也引起了人们的注意，在接收到诊断信号的敏感性的情况下，需要进行优化传感器数量及其在被测对象上的分布的过程。

Evaluation of the Suitability of the Strain-Gauge Method for Measuring Deformations during the Fatigue Tests of Aviation Composite Structures

Abstract The paper discusses the results of selected fatigue tests of a motor glider’s insulated spar structure. The results of the experimental tests were used to assess the potential of the strain-gauge method for diagnosing the spar damage involving the unbolting of one of metal fittings in the spar pin. The usefulness of the deformation measurement method in the composite structure diagnostic process was confirmed, while simultaneously drawing attention to the need for conducting a process optimizing the number of sensors and their distribution on a tested object, in the context of the sensitivity of diagnostic signals received.
