  1. 1The challenge

    Equipment that must work after the blast

    Electronics inside military containers and bunkers must keep working after shock and seismic events. Rubber is not an option: it burns, ages and loses its properties.

  2. 2The solution

    Metallic energy absorbers under the floor

    The shelter floor is a concrete slab suspended on Silentflex metallic energy absorbers. They work in all three axes, never fail completely under overload (an excess of shock turns them into a stiffer absorber) and last longer than the structure they protect.

  3. 3The result

    Tested for shock and earthquake

    The system was shock-tested with 10 tonnes of horizontal energy absorption and seismic-tested to GR-63-CORE at 1.65 g (16.5 m/s²), in the vertical and horizontal directions.
