蜂窝结构抗拉压性能实验研究及其数值模拟

文中对PVC材料圆形错排蜂窝结构的拉压等效模量及抗拉、抗压强度进行了实验研究,并利用ANSYS进行了三维有限元数值模拟.通过实验结果和数值模拟结果的比较得出,拉伸情况下,等效弹性模量和拉伸强度受夹具与蜂窝结构间的粘胶性质影响比较大;压缩情况下,等效弹性模量和压缩强度大于拉伸情况,并且结构的主要破坏形式为剪切破坏。对蜂窝结构进行强度设计必须以实验数据为依据。

Tensile and Compressing Properties Study of Honeycomb Structure by Indoor Testing and Numerical Analysis

In this paper.experimental testing and three dimensional finite element(FE) simulations are carried out to obtain the equivalent Young's modules and strength of rotundity honeycomb configuration under uniaxial load.The compressing equivalent Young's modules and strength are bigger than that of tensile case.The tensile strength and Young's modules are great affected by the glue condition between clamp and the sample.The main type of failure is the break of the glue for tensile case and shear mode failure for compressing case.
