AI Technical Summary
Existing aluminum panels are prone to continuous low-to-medium frequency vibrations when subjected to wind pressure, mechanical vibration, or sound wave impact, leading to fatigue damage of the panels and the transmission of vibration energy to the main building structure. Furthermore, their low damping makes them unable to effectively absorb mid-to-high frequency air noise.
A first damping plate, a partition plate, a second damping plate, a constraint damping layer, and a microporous sound-absorbing felt are set inside the aluminum single panel. Combined with limiting components and bolt connections, a multi-layer damping structure is formed. Vibration energy is converted into heat energy through the internal friction and shear deformation of the rubber-based material, while noise is absorbed by the microporous sound-absorbing felt.
It effectively suppresses low- and medium-frequency vibrations, absorbs mid- and high-frequency noise, improves the shock absorption effect of aluminum panels, prevents fatigue damage to the panels, and reduces vibration transmission to the building structure.
