倒翻陀螺倒翻过程的动力学分析

Dynamical Analysis for Overturn Spinning Top in Its High-Speed Spinning Process

一种常见的玩具陀螺─—倒翻陀螺在有摩擦的平台上高速旋转时，会自行翻转倒立，并继续旋转和进动．本文对这一物理现象从动力学方面进行了分析和计算．进一步阐明了这一物理现象发生的原因．

A common toyspinning top (the over-turn spinning top) doing high-speed rotation on the platform with the fortion can automatically perform the over-turn, the upside-down, the ro tation and the procession. This paper carries on the dynamical analysis and calculation for the physical phenomenon and explains the m of this phenomenon still further.
