This seminar systematically explains the fundamentals of vibration phenomena in rotating machinery from both theoretical and experimental data perspectives.
Using practical methods such as rotational order ratio analysis and tracking analysis, participants will learn the full workflow from cause identification to countermeasure planning.
In addition, the course covers imbalance correction, bearing and gear vibration, cepstrum analysis, and fault prediction using machine learning, aiming to develop practical analytical and decision-making skills applicable immediately in the field.
