Advanced Machinery Diagnostics Seminar with Structural & Piping Vibration Analysis

Advanced Machinery Diagnostics Seminar with Structural & Piping Vibration Analysis

A Training Seminar for Rotating Equipment Professionals Who Need to Get the Most from Their Machinery.

Seminar Objectives

This seminar is recommended to those who wish to gain advanced machinery diagnostic skills required to solve complex vibration problems in critical plant rotating machinery and in structural and piping vibration. The seminar will concentrate on vibration in fluid-film bearing rotating machinery critical to power generation and petrochemical refining and on structural and piping vibrations. Students will learn how machine design, support structure and piping determine vibration levels and how to evaluate the effectiveness of solutions including component modifications.

Seminar Description

Seminar topics will include:
  1. Practical basis for understanding vibration in rotating machinery and the principles of rotordynamic behavior
  2. Calculation of rotor system stiffness parameters and forces
  3. Use of rotordynamic modeling to simulate rotating machinery vibration characteristics and critical speeds, to perform root cause analysis of malfunctions and to evaluate the overall effectiveness of solutions
  4. Use of stability analysis techniques including root locus. Additionally, the use of critical speed maps and interference diagrams to evaluate resonance problems
  5. Rotor mode and deflection shape analysis
  6. Determination of acceptable vibration limits
  7. Bearing types, their influence on vibration characteristics and bearing failure modes
  8. Affect of couplings and coupling changes on vibration
  9. Structural and piping vibration theory and problem solutions
  10. Case history reviews

Who Should Attend

This seminar is designed for:

  1. Rotating equipment engineers with responsibility for specification, acceptance and reliability of critical plant rotating equipment.
  2. OEM designers of rotating equipment who require the ability to model rotordynamic behavior and the ability to evaluate the rotordynamic effectiveness of design solutions.
  3. *Professional Development Hours: This seminar provides 40 professional development hours (PDHs) toward professional engineering licensure.
