doi:10.1007/s12204-023-2587-x

Abstract

Abstract: It is particularly important to explore the response and transmission characteristics of shoe sole when exposed to foot-transmitted vibration (FTV) in daily life. In this study, based on mechanical mobility and vibration transmissibility, the vibration response and transmission characteristics of ordinary sole and multicellular structure sole under three excitation modes were analyzed with finite element analysis. The analysis results of the ordinary sole are as follows: The distribution and transmission of vibration energy of ordinary sole are more related to the excitation position and mode-shape; the phalange region is more violent in vibration response to vibration and transmission of vibration. In addition, the analysis results of multi-cellular structure soles show that different types of multi-cellular structure soles have different effects on the equivalent mechanical mobility and the equivalent vibration transmissibility, among which Grid type has the greatest influence. So, this study can help prevent foot injury and provide guidance for the optimal design of the sole.

摘要： 在日常生活中，探究足鞋振动能量的响应与传递特性尤为重要。本文采用有限元分析方法，结合机械导纳与振动传递率理论，研究普通鞋底与多胞结构鞋底在3种激励工况下的振动响应及振动传递特性。对普通鞋底的力学分析结果表明：激励位置与振型对普通鞋底的振动能量分布与传递产生显著的影响；趾骨区域的振动响应和振动传递更为激烈。同时，多胞结构鞋底的振动特性分析结果表明，不同类型的多胞结构鞋底对等效机械导纳与等效振动传递率产生不同程度的影响，其中Grid型多胞结构鞋底的振动响应与传递最为显著。本研究有助于预防足部损伤，并为鞋底的优化设计提供理论指导。
