人体脊柱动态失稳的临界载荷确定

The Determination of The Critical Load under the Spinal Dynamical Bulking

本文根据人体垂直振动特性,建立人体脊柱动力学连续体模型。分别给出人体脊柱动态失稳临界载荷、导致脊柱失稳临界加速度和矢状面内振动理论公式。

In this paper, according to the property of the humans spinal vertical vibration, the dynamical continum model is founded.The critical load of the human's spinal dynamical bulking and the critical acceleration resulting in the Spinal bulking as well as the theortical formulation of vibration in the sagittal plane are given.
