Floating Floor Vibration Isolation
Spring isolators mounted onto a steel reinforcement grid to build a floating floor for an anechoic chamber, isolating low frequency vibration from the ground.
Project Highlights
- Steel grid with spring isolators
- Load and stiffness calculated at each point
- Decouples low frequency vibration
Low frequency vibration is a hidden source of interference for an anechoic chamber and for precise measurement. To address it, Anteck builds a floating floor between the foundation and the room floor: a steel reinforcement grid is first erected, after which spring isolators are installed at calculated positions, decoupling the entire room floor from the building structure with respect to vibration.
In this photograph the engineers are installing and leveling the isolation units point by point, with the load and stiffness at every support calculated in advance to achieve the target isolation frequency. This procedure forms the basis of the chamber noise floor and measurement accuracy.
