Relationship between acoustic emission signal and loads on pneumatic cylinders

Relationship between acoustic emission signal and loads on pneumatic cylinders

Článek WoS

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.
