Springs - Import export

4-sided removable cover in Silver with natural anti-bacterial and anti-static properties thanks to silver ions. Soft hypoallergenic fibre for the upper part, breathable fabric on the lower part of the mattress that ensures air circulation. Pocket spring mattress comprising 7-zone memory foam layer with massage function, high bearing capacity Aquafoam pocket spring sheet with 800 pocketed springs. This allows a progressive and self-modelling reaction. The set of springs distributed over SEVEN ZONES responds with pressure proportional to weight, allowing the mattress to follow the body’s natural shape in a balanced manner.

Spring fluid viscous dampers are cylinder/piston assemblies characterized by a constitutive bond in which reaction force F depends both on speed v and on displacement x, according to law F=F0+Kx+Cvα, where F0 is pre-load force (if any), K is stiffness, C is the damping constant and α=0.15. Pre-load force can be useful to avoid displacements for horizontal service actions. Experimental hysteretic cycles of a spring fluid viscous damper without pre-load force. Spring fluid viscous dampers for the Badia Nuova flyover on highway A1. Spring fluid viscous dampers installed in Rio Higuamo Bridge (Dominican Republic).
