不同材质及结构的鞋底吸震回弹性能的研究

Study on the Shock-absorbing Resilience Properties of Shoe Soles with Different Materials and Structures

  • 摘要: 探讨不同材质/结构的鞋底对吸震回弹性能的影响。依据福建省地方标准DB35/1937–2020《鞋类产品吸震回弹性能试验方法》,测试三种不同材质/结构鞋底的吸震回弹性能,通过单因素方差分析模型进行统计分析,并采用同一种样品连续试验和实验室间比对试验进行数据可靠性验证。试验结果证明:依据上述标准的试验机和试验方法测得的数据是稳定可靠的,不同样品类型对于最大加速度、压入深度、回弹高度三个冲击指标均呈显著性差异,在三种不同材质/结构鞋底中,“爆米花”材质的鞋底展现出最佳的吸震回弹性能,达到了57.2%;其次是采用普通气垫结构的鞋底,性能为44%;而普通发泡材质的鞋底表现最差,仅为39.6%。

     

    Abstract: This work explored the effects of different materials and structures of shoe soles on the shock-absorbing resilience performance. According to the Fujian provincial local standard (DB35/1937-2020) "Test method for shock absorption and resilience performance of footwear products", the shock absorption and resilience performance of shoe soles with three different materials and structures were tested, statistically analyzed by analysis of variance, and the reliability of the obtained data was verified by using the same kind of samples in successive tests and the inter-laboratory comparative tests. The test results proved that the data measured by the test machines and test methods based on the above-mentioned standard were stable and reliable, and there were significant differences in the three impact indexes of maximum acceleration, indentation depth, and rebound height among the different sample types. Among the three different materials and structures, the "popcorn" sole showed the best shock-absorbing resilience performance with 57.2%, followed by the sole made of ordinary air cushion structure with 44%, and the sole made of ethylene-vinyl acetate copolymer material showed the worst performance with only 39.6%.
