IEME and LAEDE played a key role in the execution of this engineering project, carried out by the construction company Álya. IEME was responsible for preparing all the track designs, including a complete study of the vibration attenuation system (mass-spring). LAEDE, in turn, was responsible for conducting the field and laboratory tests required for the permanent way’s approval.

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.
