Abstract: For application of composite sandwich panels in the plate-cone reticulated shell, the mechanical characteristics are studied. The overall performance of the structure was analyzed based on ANSYS software, and the local buckling capacity of the composite sandwich plate was analyzed in consideration of the local buckling influencing factors. The comparative analysis of the ordinary plate-cone reticulated shell is also made. The results reveal that the structure has a large overall stiffness. Compared with ordinary plate-cone reticulated shell, it has the same static law and the composite sandwich plate has a good strength reserve. The influence factors of local buckling of sandwich plate are analyzed and some important conclusions are obtained, and it also has more advantages than ordinary plate-cone reticulated shell in terms of mechanical characteristic.

Key words: plate-cone reticulated shell, composite sandwich plate, mechanical characteristic
