人体跳跃过程中的动力学模型研究

Kinetic Model of the Human Jumping Process

跳跃是人类最基本的运动形式,也是人类的基本活动技能之一,是人体运用自身的能力或借助一定的器材,通过一定的运动形式,使人体腾越尽可能的高度或远度的运动。文中通过爱捷运动图像测量系统对运动员运动过程进行解析,得到图片、相关参数以及分析结果,在总结人体跳跃过程特点的基础上,建立三段式多刚体(弹簧-质量)人体跳跃模型,并推导出其运动方程。

Jumping is a basic human activity and one of the most basic human skills, and a kind of movement that human beings, with their own ability or certain equipment through certain forms of exercise, jump as far or as high as possible. This paper, through Aijie Movement Image Measurement System, analyzed the athlete＇s sports process, got pictures, the related parameters and the results. Based on the characteristics of the human skipping process, a three-stage and multi-rigid （spring-quality） human hopping model was established. Furthermore, its equation of motion was deduced.
