摘要
为了分析人体步态运动中包含肌骨系统的下肢动力学特性,基于生物力学分析软件AnyBody建立一种包含肌骨系统的下肢运动模型。利用逆向动力学,在下肢运动关节等处设置运动控制点,以运动控制点三维坐标和地面支反力为驱动,完成了人体的正常步态仿真,得到了人体正常步态下的踝关节和膝关节的角度、力矩的变化曲线,分析了关节力矩与角度变化之间的关系;给出了比目鱼肌、缝匠肌、胫骨后肌和胫骨前肌在步态周期内的肌肉力和活性变化曲线,讨论了肌肉力和肌肉活性之间的关系。
In order to analyze the dynamic characteristics of the lower limb including the musculoskeletal system in human gait movement, the lower limb motion model including the musculoskeletal system are established by using a biomechanics software, AnyBody^TM Modeling System. By using the reverse dynamics, the human body is driven by the three-dimensional coordinates of the motion control points set on the lower limb joints and the ground reaction force. Then the normal gait simulation of the human body is completed. The curves of the angles and moments of the ankle joint and knee joint in the normal gait are obtained, and the relationship between the joint torque and the angle is analyzed. The curves of the muscle strength and muscle activity of the soleus, sartorius, tibialis posterior and tibialis anterior muscle are given in the gait cycle. The relationship between the muscle strength and activity is discussed.
