AI Technical Summary
Existing frame-type acoustic metastructure composite panels, while taking into account load-bearing capacity, have weakened the sound insulation effect in the low-frequency range, which limits their application in fields such as rail transportation and aerospace.
The design of the frame-type sound-insulating load-bearing superstructure panel is divided into an upper panel, an acoustic superstructure interlayer, and a lower panel. By utilizing the coupling effect between the acoustic superstructure cells and the panel layers, the structural sound transmission path is reduced. Low-frequency broadband sound insulation is achieved by using local resonant units and gradient parameter coupling. The load-bearing performance is optimized by combining the resonant technology of the frame and the membrane.
While taking into account load-bearing capacity, it significantly improves the sound insulation performance in the low-frequency range, achieving a superior integration of sound insulation and load-bearing functions to meet the needs of engineering products.
