篮球过人中的膝盖成角受力模型分析与仿真

摘要

Since the current two-freedom driving torque tracking analysis method has low fitting accuracy to the force,a knee angulation force modeling method for breakthrough in basketball sports is put forward,which is based on the creeping load transitivity mechanical analysis. The knee angulation force transitive relation model for breakthrough in basketball sports was con-structed. The human body kinematics model was constructed in Cartesian space. The creeping load transitivity analysis method is used to get the damping weight of the knee angulation force and forward kinematics model under the stress state to analyze the knee angulation force model. The experimental results show that the knee angulation force model for breakthrough in basketball sports has high estimation accuracy of the mechanical characteristics,and the parameter fitting such as knee angulation is accurate.%针对当前的二自由度驱动力矩跟踪分析方法对受力的拟合准确度不高的问题,提出基于徐变荷载传递性力学分析的篮球过人中的膝盖成角受力建模方法.首先进行篮球过人中的膝盖成角受力传递关系模型构建,然后在笛卡尔空间中构建人体运动学模型,采用徐变荷载传递性分析方法得到膝盖成角受力的阻尼加权,得到受力状态下的正向运动学模型,实现膝盖成角受力模型分析.实验结果表明,采用该模型进行篮球过人中的膝盖成角受力模拟,对力学特征的估计精度较高,对膝盖的位形角等参量拟合准确.
