摘要
继笔者《牛顿定律的广义形式》一文之后,本文进一步提出广义Newton-Euler动力学方程。它较之著名的能量函数式的Lagrange方程,物理概念较为明确,运算更为简便。
The Generalized Newton-Euler's Equations of Dynamics, presenting a new approach for the dynamical calculations of rigid bodies is formulated in this paper. They arc more clear in physical concepts and simpler in calculations compared with the famous Lagrange's Equations in terms of energy functions.
