ABSTRACT This paper demonstrates the relationship between acoustic emission (AE) method parameters and loaded pneumatic cylinders. The cylinders in our experiment were loaded gradually by different weights in a vertical direction. The effect of the defect occurs when the cylinder is loaded at the retreat and progress strokes. This defect affects the relationship between the applied load and the recorded signal of the sensors. The signals of the acoustic emission were recorded from the progress and retreat strokes and then analysed. The time delay is calculated between the digital input and the initiation of movement, and the time of the stroke. The energy and root mean square of the acoustic emission compare between the distinctive different responses in damaged and undamaged pneumatic cylinders, with and without loading. The energy and RMS were calculated for each cylinder with gradual loading. The results of the test showed approximate linear relationship between the RMS and loading. This paper is a continuation of a previous article and the extension of my work to find distinctive differences that determine whether the cylinder is damaged or undamaged.

声发射信号与气缸负载的关系

摘要 本文论证了声发射 (AE) 方法参数与加载的气缸之间的关系。我们实验中的气缸在垂直方向上逐渐加载不同的重量。当气缸在后退和前进行程加载时,就会出现缺陷的影响。这种缺陷会影响施加的负载和传感器记录信号之间的关系。从前进和后退行程中记录声发射信号,然后进行分析。时间延迟是在数字输入和运动开始之间以及行程时间之间计算的。声发射的能量和均方根比较了损坏和未损坏气缸在加载和未加载时的不同响应。每个气缸的能量和 RMS 是通过逐渐加载计算的。测试结果表明RMS和负载之间近似线性关系。这篇论文是上一篇文章的延续,也是我工作的延伸,以寻找确定气缸是否损坏或未损坏的显着差异。
