人体步行运动的关节力学研究

利用角度传感器和步态测力板,本文观察了人体的步行运动,采用Fourier数字滤波拟合出各关节的运动规律,依据多刚体动力变分原理建立了适合作实时计算和模型修改的人体步行动力学方程。对于步行中双脚着地时出现的闭环结构,作者借助测力板测出的脚底反力曲线,提出了由力——位移组成的混合求解法。用文中计算方法编制的软件可用于人体下肢疾病的临床医学诊断。

STUDY OF JOINT MECHANICS IN HUMAN WALKING

In this paper, the human walking is observed by using angle sensorsand force measuring plate of gait. The movements of each joint are fit-ted by Fourier digital filter. Based on variational method of .Multi-Rigid-Body, the dynamic equation of human walking is established su-(Continued on page 6 )(Continued from page 49 )itable for both on-line caloulation and model revision. With the aid offoot reaction force ourve induced from experiment results, the combi-ned method of force and displacement is suggested by the author sothat the close-loop struoture appearing during standing on both feetmay be solved. The software compiled by the calculation method in thepaper can be used for olinical diagnosis of human leg diseases.
