Journal ArticleDOI
Investigation of the relationship between engine valve leakage and acoustic emission measured on the cylinder head ignoring combustion effects
TL;DR: In this article, the authors investigated the relationship between valve leakage and the acoustic emission generated from the steady flow in the cylinder head of the internal combustion engine and showed that acoustic emission energy and valve leakage parameters have a linear correlation.
Journal ArticleDOI
Bayesian uncertainty quantification for guided-wave-based multidamage localization in plate-like structures using Gibbs sampling:
TL;DR: A new Bayesian approach for guided-wave-based multidamage localization by employing Gibbs sampling that not only identifies the group velocity but also localizes multiple defects by sharing the same characteristics of damage localization.

AE Condition Monitoring: Challenges and Opportunities
TL;DR: In this article, the authors discuss some of the problems facing acoustic emission users, as well as suggest ways forward to overcome present challenges and obstacles, and suggest ways to overcome past failures.
Journal ArticleDOI
Research on the generalisation method of diesel engine exhaust valve leakage fault diagnosis based on acoustic emission
TL;DR: Wang et al. as mentioned in this paper proposed a novel fault diagnosis approach for diesel engine valve leakage fault diagnosis to transfer from one operating condition or type (source domain) to another (target domain), to enhance the generalization of fault diagnosis.

Stress Waves in Solids
TL;DR: A large and growing number of original papers on both the experimental and the theoretical aspects of stress wave propagation is appearing in the scientific literature, and two international conferences solely concerned with the subject have been held during the last five years as mentioned in this paper.

Source location of acoustic emission in diesel engines
TL;DR: In this paper, two source location techniques, a traditional wave velocity-based and an energy-based technique, using triangular sensor arrays, are used to locate source positions on the cylinder head of a 74kW diesel engine using simulated sources (pencil lead break) and real sources (e.g. injectors and exhaust valves during engine running).
Journal ArticleDOI
The development of automated pattern recognition and statistical feature isolation techniques for the diagnosis of reciprocating machinery faults using acoustic emission
TL;DR: The ultimate aim of the work, of which this paper is a part, is to provide a means of on-line automatic monitoring of reciprocating machines using AE without recourse to any additional sensors.

AE mapping of engines for spatially located time series
TL;DR: In this article, the authors presented the first step towards using multiple acoustic emission (AE) sensors to produce spatially located time series signals for a running engine, which is meant the decomposition of a multi-source signal by acquiring it with an array of sensors and using source location to reconstitute the individual time series attributable to some or all of these signals.
