摘要

摘要: 为揭示穿孔箔横向等效弹性模量与穿孔箔结构参数(孔隙率、孔形状、孔分布)之间的内在联系,根据均匀化理论,采用有限元分析软件ANSYS对穿孔箔的单位胞元进行模拟与分析,结果发现穿孔箔的横向等效弹性模量主要是由孔隙率决定,孔隙率越多,横向等效弹性模量越小;孔形状、孔分布对横向等效弹性模量也有一定的影响,孔隙率越多,影响越明显.减少孔的横向截面积,有利于穿孔箔横向等效模量的增加.最后通过实验对模拟结果进行验证,结果表明有限元法模拟结果存在一定的误差.

Abstract: In order to discover the relationship between the transverse equivalent modulus of elasticity and parameters(porosity,hole shape,hole arrays) of metal perforated foil,the mechanical properties of the unit cell of metal perforated foil is studied by using finite element analysis software ANSYS according to homogenization theory in this paper. The results show the transverse equivalent modulus of elasticity for metal perforated foil is mainly determined by porosity,the larger the porosity,the less the transverse equivalent modulus of elasticity; Hole shape and hole arrays have some influence on the transverse equivalent modulus of elasticity,the influence is more obvious with the increasing of porosity. Reducing the transverse area of hole is beneficial to increase the transverse equivalent modulus of elasticity. Finally,the numerical results are verified by experiments,the results show that some errors exist in FEM simulation results.
