Advanced Machinery Diagnostic
Course Description
This course provides attendees the training needed to extend their knowledge of machinery diagnostic techniques and rotor dynamics as applied to rotating machinery. In particular, they will learn the use of synchronous and non-synchronous perturbation testing to evaluate complex dynamic stiffness in rotor/bearing/seal systems, including its modal parameters, and see how to bring analytical model response predictions in closer agreement with actual machine data. The class also examines how rotor torsional modes are coupled with lateral modes, and how that information may be used for early detection of shaft crack.
The Training Course Will Highlight ?

Attendees will learn how to model machinery operation and malfunctions in fundamental terms, preparing them to better identify and understand machinery problems in the field.

 

Training Objective

  • give an account of common strategies and methods to plan and perform machinery maintenance,
  • give an account of common failures in primarily rotating machinery and how vibration analysis can detect failure, 
  • give an account of different types of transmitters and their properties when measuring mechanical vibrations,
  • plan, perform and interpret the results of condition check with vibration measuring,
  • assess a measured vibration result with the help of relevant norms,
  • balance a rotor on the principle of single-plane balancing using appropriate instruments,
  • outline some simple methods of lubrication analysis.

Target Audience

  • Engineers desiring to advance their machinery vibration diagnostics skills
  • Engineers involved in the design, acceptance testing, and maintenance of rotating machinery
  • Post-graduate engineering attendees
  • Academic researchers and professors involved in rotor dynamics
