| 摘 要： | 蜂窝结构以优异的力学性能,如比刚度大、比强度大、重量轻、良好的隔音隔热等,在建筑、工业锅炉、航空等结构中得到广泛的应用。抗剪性能是蜂窝结构主要力学性能之一,本文利用剪切实验和四点弯曲实验对PVC材料的圆形错排蜂窝结构的等效剪切模量及抗剪强度进行了实验研究,并利用有限元软件ANSYS对两种实验进行了三维有限元数值模拟。两种实验测得的等效剪切模量结果和数值模拟结果比较吻合。结果表明可以通过数值模拟对蜂窝结构的力学性能参数进行估算,并通过数值模拟为实验设计和工程实际设计理论依据和指导。

| Abstract: | In this paper,experimental testing and three dimensional finite element(FE) simulations are carried out to obtain the equivalent shear modules and shearing strength of the rotundity honeycomb configurations.One of experimental testing methods is block-shear testing and the other is one-quarter span four point bend shear testing.The results of equivalent shear modules of both experimental testing methods and the three dimensional finite element simulations are accorded with each other. |
