Do not panic. It’s not an earthquake.
This is Vibrodina at work in LAEDE.
The equipment is used for dynamic testing of forced vibration in metro-railway systems (video) and large structures such as stadiums, bridges, viaducts, dams and buildings. The test allows measuring the following dynamic properties: natural frequency of the system, damping, dynamic stiffness and fatigue performance.
LAEDE performs mechanical tests to verify resistance and reliable performance, using state-of-the-art equipment, and is part of the RBLE, accredited by Cgcre in accordance with ABNT NBR ISO/IEC 17025.
