摘　　要：利用生物力学仿真软件LifeMOD,根据关节力矩模型和肌肉力学模型,建立了用于多刚体分析的三维人体动力学模型。采用载人飞行器在着陆过程中的边界条件,模拟了乘员坐姿承受水平方向冲击作用时头颈部脊椎的动态响应。对航空航天领域中各种致伤因素下乘员脊椎骨骼损伤的研究有一定的意义,同时也为优化防护结构、保障乘员生命安全提供了一定的参考。Based on the joint torque model and the formulation of the active muscle ,the 3D multibody model for human has been constructed using LifeMOD. According to the boundary condition in landing process of aircraft,the dynamic response of pilot＇s head and cervical vertebrae has been investigated when the pilot is subjected to horizontal impact with sitting position. This method of modeling may be helpful for the pilot＇s spine injured biomechanics research,and it is also valuable for the optimization of aircraft security configuration and protecting pilots from deathful damage.
