滚动刚体的矢量场

The vector field of a rolling rigid body

George W. Patrick

摘要:

非完整系统是一类常用于描述具有理想无滑移约束的力学系统的变分模型。本文利用半辛形式,利用形状算子(又称形状算子),对任意表面上滚动的任意刚体的非完整运动方程进行了微分几何推导。Weingarten地图)。通过半辛约化,证明了在曲面为水平面的情况下,著名的微分方程是半辛的。

英文摘要:

Nonholonomic systems are variational models commonly used for mechanical systems with ideal no-slip constraints. This note provides a differential-geometric derivation of the nonholonomic equations of motion for an arbitrary rigid body rolling on an arbitrary surface, via the semi-symplectic formalism, and in terms of shape operators (a.k.a. Weingarten maps). By a semi-symplectic reduction, the well-known differential equations in the case where the surface is a horizontal plane are shown to be semi-symplectic.
