摘要 以新型高性能X-cor夹层结构为对象,实验研究了Pin的植入角为30°和体积分数为0.49%的情况下,X-cor夹层结构的纵向剪切模量。与纯泡沫夹层结构相比,X-cor夹层结构密度增加24%,剪切模量提高近7倍。在实验基础上,建立了X-cor夹层结构有限元分析模型,分析了Pin植入角、Pin直径以及Pin分布密度对X-cor夹层结构剪切模量的影响。有限元计算与实验结果对比表明,该有限元模型预测值与实验结果误差很小。 The longitudinal shear modulus of the X-cor sandwich structure with 30° Pin angle and 0.49M Pin volume fraction is studied compared with the foam sandwich structure. The longitudinal shear modulus of the X-cor sandwich structure increases by 7 times with an only 24% increase in its density. Based on the experiment, a finite element analysis model is established to predict the longitudinal shear modulus of X-cor sandwich structures. The influences of the angle, the diameter and the distributing density of Pin on the longitudinal shear modulus of X-cor sandwich structures are analyzed using the finite element model. The result proves that prediction results with the finite element model are in good agreement with experimental data.
