Crystal Instruments is excited to offer an upcoming Modal Measurement Seminar in Seattle, WA with lead instructor Dr. Pete Avitabile. From October 8-9, 2019, attendees of our special modal seminar will receive the use of a complete lab kit for the entire duration of the training seminar. Each lab kit includes a Spider-20 wireless analyzer, laptop, and modal hammer.
Agenda for October 8, 2019:
8:15 - 9:50: Overview of Experimental Modal Analysis and Measurements Required
10:00 -10:30: Impact Basics - Hammer, Tips, Force, Accelerometers
10:30 -11:00: Shaker Basics - Shaker, Amplifier, Force, Impedance
11:00 -11:50: Perform a basic experimental modal test - overview the process: make measurements
(Lunch break)
1:00 - 2:00: Modal Primer - A Brief Overview of the Process
2:00 - 2:50: Hammer - Tips; Force/Exponential Window; Coherence - example measurements
3:00 - 3:50: Hammer - Double Impact; Over/Underload/Saturation - example measurements
4:00 - 5:00: Hammer - Multiple Impacts; Roving/Stationary Hammer - example measurements
Agenda for October 9, 2019:
8:15 - 9:50: Shaker Excitation Signals for modal testing - example measurements (random, burst random, pseudo-random, chirp, digital stepped sine)
10:00 -11:00: MIMO-FRF, Multiple Coherence - example measurements (or previous data) (Shaker independence/PCA, shaker anomalies, number of shakers)
11:00 -12:00: Measurement Inconsistencies from Poor Testing - Implications for Modal Test
(Lunch break)
1:00 - 2:00: Impact Testing - Additional Items for consideration Frequency Range - Multi-bands; Skewed Inputs, ICP Low Frequency;
2:00 - 3:00: Shaker Testing - Additional Items for Consideration Stinger types, stinger effects, impedance heads, general shaker set up SLSO/MIIVIO, mass loading, effect on modal analysis (stability, modes extracted)
3:00 - 4:30: Closing Remarks - Q&A
Attendees are also invited to an optional dinner with Crystal Instruments. Please register here to join us for the seminar.
