文题释义:
ADAMS:ADAMS(Automatic Dynamic Analysis of Mechanical System)是目前被广泛使用的动力学建模仿真分析软件。该软件可以调用不同的人体尺寸参数来建模,并能够进行运动学与动力学参数的双向求解,从而避开繁琐的动力学方程求解过程,使得求解更加简洁。
 
摘要
背景:骨骼肌系统作为揭示人体运动形式变化的动力,其建模是人体建模的关键技术。
目的:基于UG与ADAMS的人体下肢骨骼肌建模。
方法:对6名男子分别测量身体下肢系统尺寸参数,根据采集到的下肢环节运动参数、动力学参数(地面反作用力)和下肢肌群的表面肌电信号,使用ADAMS对下肢骨骼肌建模并进行动力学与运动学双向仿真,获得动力学及运动学仿真参数,最后使用MATLAB对仿真值与实测值进行相关性分析以验证模型的可行性。
结果与结论:得出实测动力学、关节角度、环节点位移等数据与ADAMS仿真数据存在非常显著的线性相关关系。仿真结果表明,利用UG与ADAMS建立的人体下肢骨骼肌模型通过仿真计算能够有效求解繁琐的多刚体动力学问题。

Abstract:

BACKGROUND: Skeletal muscle system is the driving force to reveal the change of human body movement, and its modeling is the key technology of human body modeling.

OBJECTIVE: To establish models of skeletal muscle of human lower limb based on UG and ADAMS.
METHODS: Body size parameters of the lower limbs of six men were measured. According to the collected motion parameters of the lower limbs, ground reaction force (ground support) and electromyogram signal of lower limb muscle group, ADAMS with the dynamics and kinematics simulation was conducted to get simulation parameters, such as ground reaction force, joint force, and link point displacement. Simulation value was compared with the measured value. Finally, MATLAB was used for simulation analysis.
RESULTS AND CONCLUSION: It is concluded that the measured ground reaction force, joint angles, and link point displacement had very significant linear correlation with ADAMS simulation data. The simulation results show that a model of human lower limb skeletal muscle established by UG and ADAMS can effectively solve the tedious multi-rigid-body dynamics problems through the simulation calculation.
