2024 marks our 33rd year presenting the Hands-On Modal Testing & Analysis Seminar. Join the more than 1300+ engineers and technicians who have tested a Navcon JimBeam and a fully race prepared Porsche. At the beginning of each year, we schedule three to four modal seminars. Depending upon the registration, additional seminars are added to the calendar.
It is our goal, that upon completing this 4-day, 40-hour intensive short course, attendees will be able to plan, setup and conduct a modal test from start to finish. This is a technology-based training about methods & applications; it is “not” a vendor product training. Modal theory is presented from the experimentalist’s point of view. Attendees acquire their own data and conduct their own analysis. There is no other modal testing seminar like this; it is truly a HANDS-ON training.
The modal seminar is intended for those engineers and technicians who (1) conduct modal and/or operational deflection shape (ODS) tests, (2) develop analytical (FE) or experimental (SDM) modal models and/or (3) are responsible for overseeing modal related projects. Applications include noise and vibration trouble shooting, ground vibration testing (GVTs), FE modal validation & updating and health monitoring projects among others.
Each class is limited to 10 attendees. Attendees are paired in groups of 2 and each group is provided a Data Physics based data acquisition system, PCB Piezotronics test instrumentation, Navcon test structures, etc. Everyone will have their own computer with MEscope Modal/ODS Testing software and FEMtools software for Modal Pretest Analysis, FEM-Test Correlation and FE Model Updating.
Hands-On Laboratories: More than 50% of the time is spent conducting lab exercises.
- Fourier Analysis, and Digital Signal Processing Labs
- JimBeam Impact Testing & Measurements Lab
- JimBeam Shaker Excitation Lab
- Porsche Multi-Channel Modal Test & Porsche Sine Dwell Forced Vibration Test
- Box Beam Shaker Modal Test, Time & Frequency Domain ODS Tests and FRF-ODS Test
- Modal Test Parameter Estimation Lab
- Modal Pretest Analysis, FEM-Test Correlation and FE Model Updating Labs
JimBeam Test Structure: JimBeam is a Navcon laboratory test structure constructed of three aluminum plates fastened together using six 10-24 bolts. JimBeam is used during several Navcon laboratories including the Impact Testing Lab, Shaker Excitation Lab, Impact Modal Test Lab, Structural Dynamics Modification Lab and FEM-Test Correlation & FE model Updating Lab. JimBeam served as the Round-Robin test article at IMAC XXVII in 2009 and for a study by NASA Kennedy Space Center correlating Free-Free and Shaker test models.
