摘要: 介绍了大学物理及力学教材中对飞轮进动的描述及进动角速度计算公式的局限性,根据欧拉运动学方程对飞轮的定点转动进行了理论分析及数值计算,给出了飞轮的章动、进动及自旋的一般规律,有利于对进动的全面理解.

关键词: 进动, 物理摆, 数值分析

Abstract: The limitation of the description of flywheel precession and formula of precession angular calculation in textbooks of college physics and mechanics are introduced. Theoretical analysis and numerical calculation of flywheel rotation around fixed point are conducted acccording to the Euler equation of motion. The general rule of flywheel nutation,precession and spin is provided for understanding of precession concept.

Key words: precession, physical pendulum, numerical analysis
