复合材料夹层板在板锥网壳结构中的受力特性分析

ANALYSIS ON MECHANICAL CHARACTERISTIC OF COMPOSITE SANDWICH PLATE IN PLATE-CONE RETICULATED SHELL

针对复合材料夹层板在板锥网壳结构中的应用进行了受力特性的研究。基于ANSYS软件对结构进行了整体性能分析,考虑复合材料夹层板的局部屈曲影响因素分析了其局部屈曲能力,并与普通板锥网壳结构进行了分析对比。结果表明复合材料夹层板结构具有较大的整体刚度,与普通板锥柱面网壳相比具有相同的静力规律,同时,其具有很好的强度储备。分析复合材料夹层板的局部屈曲影响因素得到了其可用于实际工程设计的重要结论,并且在受力特性各方面,复合材料夹层板比普通板锥网壳结构具有更大的优越性。

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.
