摘要

通过分析X-Cor夹层结构平压模量预测公式的理论计算结果与试验值误差

提出了结构屈曲和Z-pin的长度差异引起的刚度折减的修正模型

并且详细分析X-Cor夹层结构刚度折减的机理;修正后的夹层结构平压模量的理论值与试验值吻合.新的预测公式为X-Cor夹层结构的设计提供依据

进而为X-Cor夹层结构新材料在工程领域的应用奠定了基础.

Abstract

Analyzing the error between theoretical result predicted by deduced formula and test data of compressive modulus

a modified model which concerned stiffness discount due to structual buckling and Z-pin length diversities was proposed

and stiffness discount mechanism of sandwich was studied.The analytical result of modified model sandwich compressive modulus was in coincidence with the test data.The theoretical formula provided basis for X-Cor sandwich design

and established the foundation for X-Cor’s practical application as a new type of material.
