Come ridurre le vibrazioni dei pannelli nei sistemi di facciate ventilate in rete?

Wind-induced vibration in ventilated mesh façades can cause noise, fatigue, and aesthetic issues. To mitigate these effects, begin by tensioning mesh panels on the supporting frame: use tension adjustment bolts or turnbuckles to apply uniform pre-tension across each panel, increasing natural frequency and reducing resonance. Incorporate vibration-damping clips or rubber washers at every fastening point; these elastomeric elements absorb kinetic energy and prevent metal-to-metal rattling. Aerodynamic profiling of the mesh—choosing perforation patterns with smaller hole diameters and lower open-area ratios in high-wind zones—reduces wind loading and vortex shedding. For expansive façades, segment panels into smaller modules to break up wind flow and lower oscillation amplitudes. In critical installations, add tuned mass dampers (TMDs) concealed behind the mesh to counteract specific vibration frequencies. Finally, verify performance with wind-tunnel testing or CFD analysis to predict and address potential vibration hotspots. By combining tensioning, damping hardware, and aerodynamic design, aluminum mesh façades can remain quiet, safe, and visually stable.
