人体椎间盘活动模型分析

MODEL ANALYSIS FOR INTERVERTEBRAL DISC ACTIVE OF HUMAN BODY

本文简要分析了椎间盘活动的机理，指出椎间盘运动类似于滚珠双四面支架内运动，讨论了其运动所满足的微分方程，并分析了外力方向对腰椎间盘突出的影响。

In this paper the mechanism of intervertebral disc active was analysed. The intervertebral discwas modeled by a rollingball. The differential equations of rolling ball motion were presented, andthe influence of external force on the intervertebral disc motion was discussed.
