3D打印鞋底结构在行走状态下的摩擦力学性能分析OA

With the rapid development of 3D printing technology,the customized design of shoe sole structures has become crucial for enhancing athletic performance and comfort.However,the current research on the tribomechanical properties of 3D-printed shoe soles under different sports environments remains insufficient,particularly regarding the interaction mechanism between tread patterns and road conditions.This study aims to analyze the tribomechanical performance of 3D-printed shoe sole structures during walking through finite element analysis,with a focus on exploring the influence mechanisms of road conditions and tread patterns on the frictional properties of rubber.Additionally,it analyzes the evolution of deformation modes in the midsole and the frictional performance of the outsole under various working conditions,providing a theoretical foundation for the personalized design of 3D-printed soles.Results demonstrate that under constant external load and contact area conditions,increasing road friction coefficient and extrusion contact edges while decreasing lateral contact edges lead to gradually apparent friction-induced torsional bending of rubber contact edges,effectively enhancing friction but reducing relative contact area during sliding.Increasing rubber contact area significantly improves friction while markedly decreasing relative contact area.Forefoot structures primarily enable energy absorption and shock attenuation,while arch structures connect forefoot and heel regions,and heel structures deliver critical support strength.These findings provide valuable insights for the functional design of 3D-printed shoe soles,particularly offering theoretical support for optimizing tread patterns,material distribution,and structural stiffness matching under different sports scenarios.
