| 中文摘要: |
| 根据螺旋CT扫描和软件处理，建立踝关节骨骼、跟腱三维模型。通过对背跃式跳高踏跳中的有限元计算，获得跟腱在此动作的应力-应变变化。踏跳后期蹬离时跟腱所受拉应力最大且集中在跟骨结节附着点上6cm区域。本模型可用于跟腱的生物力学研究，为踏跳中的运动损伤提供力学数据并揭示一定的力学机理。 |
| 英文摘要: |
| 3D models of anklebone and Achilles tendon were set up according to CT scan and software processing. Through the calculations on finite elements in the takeoff of back flop high jump, the stress-strain changes of Achilles tendon were obtained. At the last stage of beating the board, the tendon bears the highest tensile stress and the stress is concentrated on the 6cm area of calcaneal attachment nodules. This model can be used for biomechanical study on Achilles tendon, providing mechanical statistics for takeoff injuries and revealing some mechanical mechanism. |
