Abstract

Abstract: The cellular structure has many advantages, which is widely used in in lots of industry fields. The application of cellular structure to the shoe sole can make it have fine buffer and power-assisted effect, but due to the lacking of structural performance evaluation, the sole cannot achieve the desired effects. Accordingly, this paper designs a multi-cell shoe sole, combines the traditional shoe sole with typical hexagonal honeycomb structure features, and the static and vibration characteristics of the traditional sole and multi-cell sole are evaluated by the finite element method, then the weight of the two soles are compared. The results show that the static deformations distributions of multi-cell sole structure are more uniform under the same condition, and the deformations of traditional sole show a trend of high in the middle and low on all sides. Besides, the fundamental frequencies of multi-cell sole and traditional sole structure are 312.62Hz and 381.11Hz, respectively, and the relative vibration deformations of multi-cell sole are also more reasonable, which reflects the multi-cell superiority of impact resistance performance. Furthermore, with the same material and size, the multi-cell sole weight is 83% of the traditional sole.
