| 摘 要： | 在本文中,为了提高金字塔点阵夹芯结构的整体等效剪切强度,提出了基于芯子和面芯界面性能协调的精细优化设计思想,并对面外剪切载荷作用下的金字塔点阵夹芯结构进行了优化设计.理论分析结果表明:基于精细优化设计思想的金字塔点阵夹芯结构中,由于综合考虑了芯子强度与面芯界面强度之间的性能协调,尽管会一定程度上降低了金字塔芯子的等效剪切刚度和等效剪切强度,但由于提高了面芯界面等效剪切强度,最终提高了夹芯结构的整体等效强度.

| Abstract: | In this paper,in order to enhance the equivalent shear strength of the pyramidal lattice truss cores sandwich structures,one refined optimal design concept,which is based on the performance harmony between the cores and interface,is brought forward to design the sandwich structures with modified pyramidal lattice truss cores.Analytical results based on the refined optimal design concept show that the equivalent shear strength of the modified pyramidal lattice cores sandwich structures may be evidently increased owing to optimum structure of the pyramidal lattice cores. |
