Visualisation of the Early-Stage Vibration of the Automatic-Gauge-Control Hydraulic Cylinder Based on the Acoustic Emission Hits-Density Imaging
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.
