COURSE OVERVIEW:

Advanced vibration diagnostics is a high-level analytical discipline used to assess the health of complex rotating machinery and identify specific mechanical and electrical faults. This course goes beyond basic monitoring to explore the intricate physics of vibration, focusing on the interpretation of complex signal patterns. Understanding the nuances of cross-channel phase, time-synchronous averaging, and cepstrum analysis is essential for pinpointing the root cause of recurring equipment issues.

The scope of this training involves the use of advanced instrumentation to capture and analyze transient and steady-state data. Participants will explore the behavior of machines during startup and coast-down, identifying critical speeds, structural resonances, and rotor instabilities. The coverage extends to the study of rolling element bearing defects using high-frequency enveloping and the diagnosis of gear faults through sideband analysis, providing a comprehensive diagnostic toolkit for any industrial environment.

Furthermore, the course addresses the integration of vibration data with other condition monitoring techniques to provide a holistic view of asset health. It delves into the use of proximity probes for orbital analysis of fluid-film bearings and the application of modal testing to identify structural weaknesses. By focusing on advanced signal processing and physical modeling, the course empowers vibration specialists to make accurate maintenance recommendations that maximize machinery uptime and safety.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

1. Apply advanced signal processing techniques such as FFT and Wavelet analysis.
2. Diagnose complex faults in high-speed centrifugal compressors and turbines.
3. Utilize phase analysis to differentiate between misalignment and structural looseness.
4. Interpret rotor orbits and polar plots for hydrodynamic bearing diagnostics.
5. Perform advanced bearing fault detection using PeakVue or HFD methods.
6. Analyze gear mesh frequencies and identify specific tooth-related defects.
7. Conduct modal analysis and bump tests to identify natural frequencies.
8. Troubleshoot sub-synchronous vibration issues like oil whirl and oil whip.
9. Implement Operating Deflection Shape (ODS) analysis for structural issues.
10. Evaluate the impact of electromagnetic forces on motor vibration.
11. Execute multi-plane dynamic balancing on complex, flexible rotors.
12. Design effective vibration isolation and damping solutions.
13. Integrate vibration diagnostics into a comprehensive reliability program.
14. Facilitate expert-level reporting and technical recommendations to management.

TARGET AUDIENCE:

This course is designed for vibration analysts (Category II and III), reliability engineers, and senior mechanical technicians who are responsible for the diagnostic analysis of critical rotating assets.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
