The Shape of What’s Shaking: Identify and visualize natural frequencies that cause resonance
1 CERTIFIED PROFESSIONAL DEVELOPMENT HOUR (PDH) AVAILABLE UPON SUCCESSFUL COMPLETION OF AN EXAM.
When machinery vibration becomes severe, resonance is often at work. Methods of testing machines for natural frequencies that cause resonance have been discussed in prior presentations. This presentation will first focus on identifying resonance and then move to methods that help visualize the vibratory motion, helping to identify solutions. Two methods will be discussed- traditional Operating Deflection Shape (ODS) analysis and video motion magnification.
- Review of testing methods
- How to visualize vibratory motion
- Operating deflection shape analysis
- Understanding video motion magnification
