摘要
目的通过广义坐标变换,构建人体参数化运动学模型,应用于人体的相对运动和绝对运动分析。方法通过对人体环节的划分和人体系统的机械化处理建立人体的多刚体模型,根据人体运动的特点,采用其次矩阵和广义坐标变换建立人体参数化运动学模型。结果通过运动分析和矩阵变换建立了通用的人体参数化运动学模型。结论通过坐标变换原理,使用齐次矩阵描述人体各个环节的相对运动方程和绝对运动方程,从而给出人体模型在特定运动条件的运动特征,并用以进行人体的步行/跑步运动分析。
Objective To build the parameter sport model of human body through the transformation of generalized coordinate,for applying to the analysis of relative sports and absolute sports of human body. Methods According to the classification of the points of human body and the mechanical resolution of human body system,the multi-rigid body model of human body was built. According to the sport characteristics of human body,the parameter sport model of human body was established with subordinate matrix and the transtormation of generalized coordinate. Results Through sport analysis and matrix transformation, a generalized parameter sport model of human body had been built. Conclusion Based on the principle of the coordinate transformation, the functions of the relative sports and the absolute sports of the each point of the human body are described with criterion matrix. The sport traits of human body model under particular sport condition, such as in application for walking/running sport analysis of human body are demonstrated.
