Analysis of nonlinear dynamic characteristics of aluminum honeycomb panels

　　针对aluminum honeycomb panel光伏构件在应用于有保温性能要求的非采光立面幕墙时，由于不能及时散热导致非晶硅电池表面温度过高的现象，设计了一种带热压通风通道的aluminum honeycomb panel光伏构件，并建立这一构件模型，Nonlinear dynamic characteristics of aluminum honeycomb panelThe heat transfer in the model was simulated and analyzed by CFD software, and the photovoltaic components of aluminum honeycomb panels with hot pressing ventilation channels and ordinary aluminum honeycomb panels were compared and analyzed.

The simulation study and experimental comparison of the nonlinear dynamic characteristics of aluminum honeycomb panels show that the photovoltaic components of aluminum honeycomb panels with hot pressing ventilation channels can take away the heat in the channels through hot pressing ventilation, reduce the surface temperature of amorphous silicon cells, and improve the power generation efficiency of thin film solar cells.

　　Beijing honeycomb aluminum plateIt is a composite material with large surface formed by hot pressing of high-grade aluminum alloy panel, back plate and aluminum honeycomb core material. The product specifications are various, and the surface can be embossed, mirror, embossed, wire drawing, electroplating, anodizing, matte, bright light and metallic color, etc., which can meet the application requirements of various places.

In order to study the nonlinear dynamic characteristics of composite aluminum honeycomb sandwich panels commonly used in spacecraft, random excitation vibration tests were carried out on beam-like aluminum honeycomb sandwich panels under different excitation magnitudes.
