Engineering Vibrations Lab
In our engineering vibrations lab, we conduct experimental analysis of composite building models, both with and without fluid viscous dampers (FVD), to study their dynamic responses under various loading conditions. We utilize viscoelastic models such as the Generalized Maxwell, Kelvin-Voigt, and Rayleigh models to accurately characterize material behavior, ensuring our advanced finite element analysis (FEA) simulates real-life structures effectively; this is complemented by 3D printing techniques to fabricate parts that are integrated into our composite models for comprehensive vibration testing.
