Abstract

By taking into account the hits-density imaging technique that has been introduced by authors’ previous publications, the acoustic emission bursts emitted from the automatic-gauge-control hydraulic cylinder under normal loading and early-stage vibration were investigated. First, six acoustic emission descriptors that showed significance regarding the cumulative probability distribution were visualised, followed by the reconstruction of the hits-density images using these features; Through the visual examination of the hits-density images regarding the cylinders’ normal loading and early-stage vibration, apparent visual differences between normal and early-stage vibration under the same loading can be observed; By projecting the hits-density images onto the principal component space, a trajectory which represents the condition developments was observed, which shows a visual-based resolution for dealing with vast transient bursts data reduction, reconstruction and visualisation.
