MOBIUS INSTITUTE - RELIABILITY IMPROVEMENT & VIBRATION ANALYSIS TRAINING AND CERTIFICATION PER ISO 18436
A uniquely effective three-day course for experienced vibration analysts.
ODS & Modal Analysis
Have you ever looked at route based spectrums and waveforms in alarm and couldn’t figure out the source of the vibration? Have you ever had difficulty convincing others of your diagnosis? Have you ever diagnosed resonance but didn’t have a recommendation for correction?
Operational Deflection Shape (ODS) and Modal Analysis are powerful diagnostic tools that allow the vibration analyst to visualize, analyze and identify corrective actions to solve vibration issues on rotating machines and structures.
Even the most experienced vibration analyst will benefit from this unique course and will learn how to use and apply these impressive diagnostic techniques.
Attendees should have a desire to “see” the deformation shape of machines and structures in a way that route based data spectrums and waveforms cannot illustrate. Analyzing ODS or Modal animations with as little as a few or hundreds of test points is extremely effective and a powerful diagnostic tool.
You will learn about planning ODS jobs, phase analysis, instrumentation requirement and how to set up your analyzer to collect time and frequency based projects, ODS data types, and use of ME’scope software to model, animate and analyze ODS projects. Case histories will be presented to illustrate and reinforce what we learn in class about ODS testing.
You will learn about planning Modal Analysis projects, resonance testing methods, Modal testing instrumentation, excitation methods, single and multiple degree of freedom test methods, use of ME’scope software to model, animate and analyze Modal projects and methods to avoid and correct resonance including using finite element tools in ME’scope software. Case histories will be presented to illustrate and reinforce what we learn in class about Modal testing.
Operational Deflection Shapes & Modal Analysis Course
When challenged with difficult vibration analysis problems where the source is not known, a resonant condition without an obvious solution, or you simply that you need to convince yourself or
others of specific diagnosis;
Operational Deflection Shape (ODS) and Modal Analysis are the right techniques
needed to solve these issues.
