不同硬度的鞋底-鞋垫组合对运动鞋减震性能的影响

Effect of the Sole-Insole Combination with Different Hardness on the Shock Absorption Performance of Sports Shoes

探讨不同硬度的鞋底-鞋垫组合对运动鞋减震性能的影响。采用冲击试验机测试3种不同硬度中底(Shore C35°、Shore-C48°、Shore-C58°)、2种硬度鞋垫(Shore C51°、Shore C71°)及1种橡胶外底(Shore-A51°)的不同组合方式,在3种冲击高度下对减震性能评测指标的影响。结论:在高、中、低三种能量冲击下,材料硬度可以显著影响鞋底-鞋垫组合的减震性能,高硬度鞋底或鞋垫组合的鞋底-鞋垫减震性能较差,中等硬度鞋底或无鞋垫组合的鞋底-鞋垫减震性能居中,低硬度鞋底或鞋垫组合鞋底-鞋垫减震性能较好。从降低脚后跟冲击损伤出发,在进行低能量冲击运动如慢走运动,建议选择低硬度的鞋底-鞋垫组合的运动鞋,在进行中等能量冲击运动如快走运动,建议选择低硬度和中等硬度鞋垫搭配的鞋底-鞋垫组合的运动鞋,在进行高能量冲击运动如慢跑运动,建议选择有鞋垫的运动鞋。

This paper discusses the effect of the combination of soles and insoles with different hardness on the shock absorption performance of sports shoes. The impact tester was used to test the impact of different combinations of three different hardness mid-soles(Shore C35°, Shore-C48°, Shore-C58°), two hardness insoles(Shore C51°, Shore C71°) and one rubber out-sole(Shore-A51°) on the evaluation index of shock absorption performance at three impact heights.Conclusion:Under the impact of high, medium and low energy, the material hardness can significantly affect the shock-absorbing performance of the sole-insole combination. The shock-absorbing performance of the sole-insole combination with high hardness sole or insole combination is poor, the shock-absorbing performance of the sole-insole combination with medium hardness sole or insole combination is medium, and the shock-absorbing performance of the sole-insole combination with low hardness sole or insole combination is good. In order to reduce the impact damage of the heel, it is recommended to select a low-hardness sole-insole combination sports shoes when performing low-energy impact sports such as low-speed walking,and the sole-inshoe combination sports shoes with low hardness and medium hardness when performing medium energy impact sports such as fast-speed walking, and the sports shoes with insole when performing high energy impact sports such as jogging.
