Abstract

Neck injuries from parachute opening shock (POS) are a concern in skydiving and military operations. This study employs finite element modeling to simulate POS scenarios and assess cervical spine injury risks. Validated against various conditions, including whiplash, the model replicates head/neck kinematics and soft tissue responses. POS simulations capture body/head motions during parachute deployment, indicating minimal risk of severe neck injuries (Abbreviated Injury Score/AIS ≥ 2) and low risk of soft tissue tears. Vertebral stress analysis during a rougher jump highlights high stress at C5/C6 lamina, indicating fracture risk. Comparative analysis with rear impact scenarios reveals distinct strain patterns, with rear impacts showing higher ligament strain, consistent with higher soft tissue damage risk. Though POS simulations exhibit lower strain values, they emphasize similar neck deformation patterns. The model's capability to accurately simulate head and neck movements during parachute openings provides critical validation for its use in assessing injury risks. The study's findings underline the importance of considering specific loading conditions in injury assessments and contribute to refining safety standards for skydiving and military operations. By highlighting the differences in injury mechanisms between POS and rear impacts, this research offers valuable insights into tailored injury mitigation strategies. The results not only enhance our understanding of neck injury mechanisms but also inform the development of protective gear and safety protocols, ultimately aiding in injury prevention for skydivers and military personnel.

降落伞打开冲击对颈部伤害的数值建模和分析。
跳伞和军事行动中,降落伞打开冲击(POS)造成的颈部损伤是一个令人担忧的问题。本研究采用有限元模型模拟 POS 场景并评估颈椎损伤风险。该模型针对各种情况(包括鞭打)进行了验证,复制了头部/颈部运动学和软组织反应。POS 模拟捕捉了降落伞展开过程中的身体/头部运动,表明颈部严重受伤的风险极小(简略损伤评分/AIS ≥ 2),软组织撕裂的风险较低。在较恶劣的跳伞过程中进行的椎体应力分析显示,C5/C6 椎板应力较大,有骨折风险。与后方撞击情景的比较分析显示出不同的应变模式,后方撞击显示出更高的韧带应变,与更高的软组织损伤风险相一致。虽然 POS 模拟显示的应变值较低,但它们强调了类似的颈部变形模式。该模型能够准确模拟降落伞打开时头部和颈部的运动,这为其用于评估伤害风险提供了重要的验证。研究结果强调了在伤害评估中考虑特定加载条件的重要性,有助于完善跳伞和军事行动的安全标准。通过突出 POS 和后部撞击在伤害机制上的差异,这项研究为量身定制伤害缓解策略提供了宝贵的见解。研究结果不仅加深了我们对颈部损伤机制的理解,还为防护装备和安全协议的开发提供了参考,最终有助于跳伞运动员和军事人员预防损伤。
