摘要 通过力学分析得到考虑Z-Pin拉压受力情况的X-cor夹层结构剪切模量的解析式,并通过剪切刚度实验值和理论值的对比分析,得到考虑刚度折减系数M的修正理论公式。结果表明:加载过程中,Z-Pin从面板拔出是剪切刚度折减的原因。通过缩小Z-Pin长度的差异及提高Z-Pin从面板拉脱力的大小增大剪切刚度折减系数M,进而提高夹层结构的剪切刚度。

Abstract:An analytical formula was derived for the shear modulus of X-cor sandwich structure based on mechanical analysis of tensile and compressive stress in Z-Pins. By comparing results from test and calculation, the modified theoretical formula of shear modulus was achieved concerning stiffness discount factor M. The results show that the stiffness discount roots in Z-Pin being pulled from face skin under load. Higher stiffness discount factor M can be obtained by bettering the craft, including decreasing Z-Pin length difference or elevating the pull-out force of Z-Pin, and then sandwich shear modulus can be further improved.
