Abstract

This study focuses on the development of a reliable prosthetic running blade primarily composed of carbon fiber. The reliable performance of novel prosthetic running blades has been evaluated by mechanical testing and finite element numerical modeling. The experimental analysis confirmed that these blades exhibit superior suitability for high-impact activities, demonstrating reliable load-bearing capacity and effective shock absorption properties. The tensile testing exhibited a linear elastic behavior of the composite material up to a strain of 0.075 mm/mm. Further, it was found that stress concentration areas and fracture points within the blade structure. Furthermore, numerical results revealed a maximum deflection of 29.60 mm that the blade can achieve. The kinetic energy loss during impact demonstrated an 8.5% decrease in blade kinetic energy, with the highest loss occurring at Vy = 30 m/s. Ultimately, this research aims to enhance the reliability, durability, and safety of prosthetic running blades, empowering athletes to reach new heights in sports.

碳纤维假体运行叶片可靠性评估

本研究的重点是开发一种主要由碳纤维组成的可靠的假肢跑刃。通过力学试验和有限元数值模拟对新型假肢跑动叶片的可靠性能进行了评价。实验分析证实，这些叶片在高冲击活动中表现出卓越的适用性，表现出可靠的承载能力和有效的减震性能。拉伸试验表明，复合材料在应变为0.075 mm/mm时表现为线弹性。进一步发现叶片结构内部存在应力集中区和断裂点。此外，数值结果表明，叶片可以实现的最大挠度为29.60 mm。撞击过程中，叶片动能损失减小8.5%，在Vy = 30 m/s时损失最大。最终，本研究旨在提高假体跑步叶片的可靠性，耐用性和安全性，使运动员在运动中达到新的高度。
