"Ground Vibration Testing (GVT)" Eğitimi
ve
Kullanıcı Konferansı

TARİH : 24-25 Mayıs 2011
MEKAN : TÜBİTAK UZAY Ankara



The aerospace industry is continuously under pressure to develop lighter components, systems, aircrafts and spacecrafts in shorter timeframes and at lower cost - without compromising quality, safety and the mission itself.

This presents two primary challenges. On one hand, engineering teams still need to ensure the structural integrity of the aircraft or spacecraft and its critical components. On the other hand, they must reduce testing time while increasing data quality and accuracy.

To shorten development times while still assuring design critical issues like structural integrity and safety, aircraft development teams are faced with several Ground Vibration Testing challenges:

- Ensure identification of all critical modes and assess their non-linear behavior
- Manage challenging logistical requirements linked to boundary conditions, structure configurations, the typical usage of high number of sensors with multiple shakers and multi-shift testing teams
- Reduce test campaign duration to match development schedule and costs
- Deliver accurate, validated and traceable reference data in support of the flutter certification process
