COURSE OVERVIEW:

Advanced machinery dynamics is a specialized discipline focusing on the complex behavior of rotating and reciprocating equipment under various operational loads and speeds. This course provides a high-level analytical framework for understanding the interaction between machine components, structures, and fluid forces. Mastery of these dynamics is essential for diagnosing recurring mechanical issues that standard maintenance practices cannot address, such as structural resonance and complex rotor instabilities.

The scope of this training involves the mathematical and physical modeling of mass, stiffness, and damping within industrial machinery. Participants will explore the principles of multi-degree-of-freedom systems, modal analysis, and the influence of support structures on overall machine stability. The coverage extends to the study of non-linear vibrations, transient responses during startup, and the orbital analysis of rotor motion within hydrodynamic bearings, providing a comprehensive view of machine health.

Furthermore, the course addresses the application of advanced diagnostic tools to interpret dynamic data and implement corrective measures. It delves into the use of proximity probes, accelerometers, and specialized software to perform ODS (Operating Deflection Shape) analysis and modal testing. By bridging the gap between theoretical mechanical engineering and field-based troubleshooting, this course enables participants to predict machinery behavior and optimize the reliability of critical plant assets.

COURSE OBJECTIVES:

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

1. Model the dynamic behavior of complex multi-degree-of-freedom systems.
2. Identify the root causes of sub-synchronous and non-synchronous vibrations.
3. Evaluate the influence of bearing stiffness and damping on rotor stability.
4. Perform modal analysis to identify structural natural frequencies.
5. Interpret rotor orbits and polar plots for diagnostic purposes.
6. Analyze the impact of foundation and baseplate dynamics on machine vibration.
7. Design effective damping solutions for resonant mechanical structures.
8. Assess the risks of oil whirl and oil whip in hydrodynamic bearings.
9. Calculate critical speeds and determine amplification factors.
10. Utilize Operating Deflection Shape (ODS) analysis to visualize motion.
11. Troubleshoot instability issues in high-speed centrifugal compressors.
12. Formulate dynamic specifications for the procurement of new machinery.
13. Conduct impact testing and cross-channel phase analysis.
14. Predict the effects of mass unbalance and shaft misalignment on dynamics.

TARGET AUDIENCE:

This course is designed for vibration specialists, reliability engineers, mechanical design engineers, and senior technical staff responsible for the health and stability of high-speed rotating equipment.

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.
