摘要
介绍一种演示刚体平面平行运动转动瞬心极迹动态关系的教具 ,可清晰的在一幅画面上演示瞬心位置移动所描绘出的空间极迹和本体极迹以及三者之间的动态关系 .教具结构简单易于制作 。
A kind of demonstrator is introduced, which can demonstrate the dynamic relation of rigid body turning centrodes in plane parallel motion. In one picture, the shifting of the instant center location can be demonstrated clearly with the description of herpolhode, polhode and their dynamic relation. The structure of the demonstrator is simple, easily making and portable to carry.
