4. Establishing an human spine dynamic model is an significan event to study spine injured biomechanics of pilot " s ejective injury , parachute opening , landing and study the endurance to impact loading on human spine . in this paper , the huston " s method of kane " s equations is developed so that it can be applied to the multibodysystem including translation between the bodyies . the dynamic model of human spine is provided basing on these theories , while the big movement of spine is considered . the deformation of vetebra is far smaller comparing with the intervetebra disc , so the spine is considered into multibodysystem including rigid bodies ( vetebra ) and the flexible bodies ( intervetebra disc ) . the computer solution correspond with the results of the large scale human impact test . the rigid coefficient factors and the damping factor of intervetebra joints are obtained
   人体脊柱动力学模型的建立对研究飞行员弹射救生、伞兵跳伞开伞、着陆等脊柱损伤的生物力学以及研究人体脊柱耐受冲击载荷的极限问题都具有重要意义.首先发展了凯恩方程的休斯顿方法，使其可应用于变形体连接的多体系统，并以此理论为依据建立人体整椎脊柱冲击动力学模型，此时考虑脊柱的大位移运动，每个椎骨的变形相对椎间盘的变形小得多，把脊柱看成由刚体(椎骨)和变形体(椎间盘)组成的多体系统.并以大型真人坐姿冲击实验结果进行了拟合，最后得到腰椎间关节刚度系数因子和阻尼系数因子
