Advanced Modal Seminar
Location: Fullerton, CA
Instructor
- Jim Steedman, Navcon Engineering Network
This three-day course is intended for both the Model Test Engineer and the Finite Element Analyst. We start off discussing Pretest Analysis and methods for selecting accelerometer & excitation locations. We then create a FE Model of a laboratory test article and head out to the lab to conduct the Modal Test . Once the model has been created and the test complete, we will perform a Correlation Analysis evaluating the initial self & cross, MAC & Orthogonality. The next step will be to conduct a Sensitivity Analysis to determine candidate model parameters for the FE Model Updating . There will also be sessions on Structural Dynamics Modification (troubleshooting, accelerometer mass loading, etc.) and Statistical Analysis . The course covers the theoretical background and approximately 60% of the time will be spent conducting laboratory tests and hands on analyses. Students are encouraged to bring notebook computers to the class. Everyone will receive a 30 day fully functional copy of the modal testing software, ME’Scope and the CAE software, FEMtools

Instructors
- Jim Berry, Technical Associates, Charlotte
- Ken Singleton, Technical Associates, Charlotte
This 4-day course provides a basic understanding on how to use Experimental Modal Analysis (EMA) and Operating Deflection Shape Analysis (ODS). The focus of this class is on applying these powerful diagnostic tools on real-world machinery and structures rather than expending class time on deriving high-level mathematical formulas (a background in differential equations and Laplace transforms will aid the student in comprehending concepts taught, but is not required today even to apply these tools to complex mechanisms & structures since such mathematics is now taken care of by the software). Knowing how to employ ODS and Modal methods have become particularly important today now that Resonance is now one of the leading (and often, The Leading) problems to which today’s machinery is subjected.
That is, the emphasis in this class will be on how to properly perform ODS and EMA measurements, how to interpret their results from computer animations, and how to formulate meaningful recommended corrective actions required to resolve problem conditions found. The students are provided with structural models of plant machinery to generate and import Experimental Modal and Operating Deflection Shape analysis measurements, and to create machinery animations. Students are then given an overview on how to: Establish a Project; Create a Structure; Import Data; Interpret data (ODS, ODS FRF, and Modal); accomplish Modal Analysis Curve Fitting; and employ Structural Dynamics Modifications (SDM) needed to predict the effect of modifications within the model before such modifications are fabricated and put onto place. However, the focal point of this class is not to learn how to use all the capabilities of an excellent software package (ME’scopeVES), but instead on how to simplify what formerly were complex methodologies making them practical and demonstrating how these powerful ODS and Modal analysis tools can be Applied on machinery and support frame/foundation problems they encounter on a daily basis.
