跳台滑雪空中飞行的动力学研究

Dynamics Research on the Flight in Ski-Jumping

将最近30年发展起来的力学新分支──多刚体系统动力学理论应用于跳台滑雪动力学研究。首先，运用目论中有向图的概念构造力学模型，并以张量和矩阵等数学工具推导出了腾空人体系统的动力学方程，然后按上述方法编制了进行数值计算的腾空人体系统动力学计算机程序（PHBD程序），经算例考证，程序使用方便，计算准确，所得结论可靠。

The theory of Multi-rigid-body system dynamics which has grown up to be a new branch of mechanics since the last three decades was applied to the research on Ski-Jumping dynamics.First,the concepts of graph theory,and the equations of kinematics and dynamics of the airborne human body were derived with tensors and matrices.Then, according to the method mentioned above, a computer program of human airborne multi-rigid-body system(PHBD program) was developed.Tested by an example,the program is convenient and accurate.
