Course Content

Day 1: Review of natural frequencies, mode shapes, and the concept of modal participation.  Introduction to methods of advanced diagnostic techniques including operating deflection shape (ODS), experimental modal analysis (EMA), video motion amplification (MA) and finite element analysis (FEA) for diagnostic studies and the development of corrective action plans.

Day 2: Review of digital signal analysis principles that effect diagnostic studies. Principles & demonstration of the impact method used to determine natural frequencies and damping.  Use of variable speed data to determine natural frequencies.  Special considerations for Shop Testing versus Field Testing.  Introduction to and demonstration of experimental modal techniques used to determine mode shapes. Verification of Modal Data.

Day 3: Review of Modal/ODS Model development.  Introduction to and demonstration of operating deflection analysis testing techniques, including common mistakes made when performing an ODS.  Review of using ODS testing as a substitute for experimental modal testing; Obtaining mode shapes with ODS data instead of modal data.

Day 4: Using EMA/ODS/FEA to diagnose and correct vibration problems in Fans and Pumps.  Using EMA/ODS/FEA to diagnose and correct vibration problems in Mixers, Gearboxes, Screens, and Other Equipment.  Using EMA/ODS/FEA to diagnose and correct vibration problems in Piping and Ductwork.
