Honeycomb is widely used because of its excellent energy absorption characteristics during compression. However, offset defects in the manufacturing process are inevitable and affect the energy absorption characteristics. In order to study the effect of offset defect, the finite element model was established firstly. The verified finite element model was used to simulate the honeycomb structure under different offsets. The simulation shows that with the increase of the offset λ, the deformation mode of the honeycomb can be divided into three stages and the platform strength increased first and then decreased, and the decrease was obviously greater than the increase. Then the theoretical calculation formula of platform strength of the honeycomb under offset defect was obtained by simple folding theory. The results show that for commonly used honeycomb specifications, when λ = 0.4, the platform strength increases the most, which is 7.99%, and when λ = 1.0, the platform strength decreases the most, which is 18.03%. The theoretical results are similar to the simulation results. For Y-shaped element, the errors are 2.13% and 2.04% at λ = 0.4 and 1.0 respectively, for whole honeycomb, the errors are 0.29% and 4.82% at λ = 0.4 and 1.0 respectively. Therefore, the platform strength of honeycomb can be improved by increasing the offset appropriately.

蜂窝由于其在压缩过程中出色的能量吸收特性而被广泛使用。然而，制造过程中的偏移缺陷是不可避免的，并且会影响能量吸收特性。为了研究偏移缺陷的影响，首先建立了有限元模型。验证后的有限元模型用于模拟不同偏移量下的蜂窝结构。仿真表明，随着偏移量λ的增加,蜂窝体的变形模式可分为三个阶段,平台强度先增加后减小,且减小量明显大于增加量。然后通过简单折叠理论得到偏移缺陷下蜂窝体平台强度的理论计算公式。结果表明，对于常用的蜂窝规格，当λ  =0.4时，平台强度增加最多，为7.99%；当λ  =1.0时，平台强度下降最多，为18.03%。理论结果与仿真结果相似。对于 Y 形单元，在λ  = 0.4 和 1.0处的误差分别为 2.13% 和 2.04% ，对于整个蜂窝，在λ处的误差分别为 0.29% 和 4.82% = 0.4 和 1.0 分别。因此，可以通过适当增加偏移量来提高蜂窝的平台强度。
