3D打印定制速滑鞋垫的系统研究:设计制作与量化验证

The Systematic Studies on 3D Printing Customised Speed Skating Insoles:Design Fabrication and Quantitative Validation

综合相关研究发现,不舒适的速滑鞋可能增加运动员足部损伤风险,而穿着定制速滑鞋垫可以有效缓解这一问题。运用文献资料、实验分析、数据分析等研究方法,对基于一名青少年速度滑冰运动员脚型设计的3D打印定制速滑鞋垫的综合性能进行研究。得出3D打印定制速滑鞋垫能在不改变运动员原有滑行姿态特征的基础上,提高足部的主观舒适度;通过增大足底接触面积、降低足底局部压强,改善滑冰过程中局部应力过于集中的问题,降低足部损伤风险;增加运动员足中区域峰值力,实现足弓区域蹬冰力向地面的主动输出。建议后续对运动员长时间穿着该速滑鞋垫进行训练后,足底压力和下肢运动学参数进行研究;作为青少年速滑运动员的辅助装备,推动定制化速滑鞋垫在专业训练和体育教学中的普及,并不断向低成本方向改进;将其设计思路和制作技术向其他冬季项目进行推广。

The comprehensive studies have found that uncomfortable speed skating shoes may increase the risk of athletes'foot injuries,and wearing customised speed skating insoles can effectively alleviate this problem.This paper hasinvestigated the performance of 3D printing custom insoles based on the foot shape of a youth speed skater by using the method of literature review,experimental analysis and data analysis.It is concluded that the 3D printing customised speed skating insole can improve the subjective comfort of the foot without changing the original skating posture characteristics of the athlete;improve the problem of over-concentration of local stress during skating and reduce the risk of foot injuries by increasing the contact area of the sole of the foot and decreasing the local compression of the sole of the foot;and increase the peak force of the mid-foot region of the athlete to realise the active output of stirrup force of the arch region to the ground.It is recommended to conduct subsequent study on the plantar pressure and lower limb kinematic parameters of athletes after wearing the speed skating insoles for a long period of time for training;to promote the popularity of customised speed skating insoles in professional training and physical education as an auxiliary equipment for young speed skaters,and to continuously improve them in the direction of low cost;and to promote its design ideas and production techniques to other winter sports.
