differential geometry在力学系统理论中的一些应用

Some applications of differential geometry in the theory of mechanical systems

M. P. Kharlamov

摘要:

本文以现代微分几何的一些概念为基础,发展了力学系统(包括陀螺力系统)的不变量理论。本文提出了一种以给定测地曲率的流动形式表示的陀螺力系统的解释。为了说明问题的刚体运动的不动点在轴对称力场进行检查。计算了简化系统的陀螺力形式。它表明,这种形式是一个产品的动量常数,体积形式的2-球,并明确书面的球上的任何地方的正函数。

英文摘要:

In the paper, some concepts of modern differential geometry are used as a basis to develop an invariant theory of mechanical systems, including systems with gyroscopic forces. An interpretation of systems with gyroscopic forces in the form of flows of a given geodesic curvature is proposed. For illustration, the problem of the motion of a rigid body about a fixed point in an axially symmetric force field is examined. The form of gyroscopic forces of the reduced system is calculated. It is shown that this form is a product of the momentum constant, the volume form of the 2-sphere, and an explicitly written everywhere positive function on the sphere.
