Master class: Ground vibration testing (GVT)

June 5-8, 2023 | NAVAIR, Patuxent River, MD, USA


The 4-day in-person ground vibration testing (GVT) master class will cover, in detail, the challenges and modern solutions for dynamic testing of full aircraft structures.
Why attend the ground vibration testing master class

The master class rolls out an integrated approach to handle the test preparation, modal testing, modal analysis, numerical model correlation, model updating, and model exploitation. All attendees will participate in an actual full-scale GVT on a grounded aircraft. In addition, during the hands-on sessions, participants will be able to rehearse the full process on a physical and virtual scale model.

To supplement the structural dynamics training experience, we will invite experts from the aviation industry to share their experiences and present on specific technical topics. The list of experts will be defined as the agenda evolves.
