一种完整约束(holonomic)反转陀螺(rattleback)
A Holonomic Rattleback
AI总结:
本研究打破反转陀螺自旋反转效应仅源于非完整约束的传统认知,提出了完整约束力学体系下也存在具有自发自旋反转特性的自旋刚体示例。
摘要:
反转陀螺(rattleback,又称凯尔特石)是一种刚体,其运动过程中会自发发生自旋反转,这一奇特效应通常被完全归因于其非完整约束特性。实际上,反转陀螺是非完整力学中的典型范例。我们提出了一个在完整约束力学框架下,运动过程中会发生自发自旋反转的自旋刚体示例。
英文摘要:
The rattleback or celt top is a rigid body with the peculiar behaviour of having a spontaneous spin reversion during its motion and this effect is usually attributed purely to its nonholonomic nature. Actually, the rattleback is the paradigmatic example in nonholonomic mechanics. We give an example of a spinning rigid body having spontaneous spin reversion during its motion in the context of holonomic mechanics.
