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
人體脊柱動力學模型的建立對研究飛行員彈射救生、傘兵跳傘開傘、著陸等脊柱損傷的生物力學以及研究人體脊柱耐受沖擊載荷的極限問題都具有重要意義.首先發展了凱恩方程的休斯頓方法，使其可應用於變形體連接的多體系統，並以此理論為依據建立人體整椎脊柱沖擊動力學模型，此時考慮脊柱的大位移運動，每個椎骨的變形相對椎間盤的變形小得多，把脊柱看成由剛體（椎骨）和變形體（椎間盤）組成的多體系統.並以大型真人坐姿沖擊實驗結果進行了擬合，最後得到腰椎間關節剛度系數因子和阻尼系數因子An iron rod or a timber used to strengthen a building, a tight bandage for the wrist and an iron frame to hold the ankle straight are all braces

測定分析了4例新鮮胸腰段脊柱標本分別處在直立、前屈20 、后伸20狀態，受到靜載荷作用時胸腰椎前緣的應力和應變分佈規律。
