单杠上人体摆动的凯恩动力学模型

Kane's Dynamics Model of Swing on the Horizontal Bar

理论建模是人们定量地认识客观事物的一种重要方法。通过运用多体动力学的凯恩方法，建立一个单杠上人体摆动的5环节多刚体系统模型，并以隐式方法推导出运动方程。该模型较国内外其他模型能够更加细致地分析单杠上人体摆动技术，并为其数值仿真奠定基础。

Modeling theoretically is an important app roach for understanding real ity quantitatively. In this paper, the human body on the horizontal bar was mode led as the 5-segment rigid multi-body system, and the motion equations were deri ved from Kane's dynamic equations. Contrasted with the other 5-degment biomechan ical models, the present model was able to analyze the technique of swing on the horizontal bar, and adequately satisfy all computer simulation needs.
