零泊松比蜂窝夹层具有独特的变形特性,适用于一维柔性蒙皮。蜂窝夹层结构等效弹性模量的研究是夹层结构设计的基础。文章在梁模型的基础上,用能量法推导了蛇形环零泊松比蜂窝芯的等效弹性模量理论公式,并将理论公式与有限元法计算结果进行了对比,验证了理论公式的正确性。
Zero poisson pine honeycomb sandwich has a unique deformation characteristics, suitable for one-dimensional flexible skin. The study of equivalent elastic modulus of honeycomb sandwich structure is the basis of sandwich structure design. Based on the beam model, the theoretical formula of the equivalent elastic modulus of the snail-shaped zero Poisson’s ratio honeycomb core is deduced by the energy method. The theoretical formula and the result of the finite element method are compared, and the theoretical formula Correctness
