Introduction:Radoslaw Zimroz and Agniezka Wylomanska are professors at the Wroclaw University of Science and Technology in Poland, in the departments of
Mechanical Engineering and Applied Mathematics, respectively. They are co-founders of the International Conference on Condition Monitoring and Machinery in Non-stationary operation (CMMNO). Their research mainly focuses on mathematical analysis and mathematical representation in mechanical fault diagnosis.
Professor Radoslaw Zimroz's presentation will focus on the application, solutions, and unresolved issues of non-Gaussian noise in mechanical fault diagnosis and
prognosis. Professor Agniezka Wylomanska will present, from a mathematical perspective, how to extract hidden periodic components from mechanical vibration signals with non-Gaussian characteristics.
Abstract:In many condition monitoring problems the informative component in the signal or extracted feature used for damage detection or future condition forecasting is associated with a noise. Most cases considered in research papers assume Gaussian distribution of mentioned noise. Unfortunately, if this assumption is not fulfilled many classical methods may not provide proper results. In the presentation we introduce the problem, we explain what could be a source of such noise from mechanical perspective, we propose some tools to understand (quantify) the scale of the problem (can methods be used or not?) and finally we discuss some future challenges.
