应用转动规范理论建立多柔体系统动力学方程

Application of Rotor Norm Theory:Formulation of a Flexible Multibody Dynamics Equation

应用转动规范理论建立惯性系与非惯性系之间的速度和加速度转换的关系式。以此为基础导出多柔体系统的速度和加速度的表达式 ,根据速度变分原理建立功力学方程。应用本文方法 ,降低了计算机存储 ,最后给出一个数值算例。

In this paper the formulation of acceleration and velocity in a inertia system transferring to a non-inertia system is presented based on rotor theory.The acceleration and velocity formulation of flexible multibody is given.The equations formulation of flexible multibody is derived on the basis of the jardon's principle.With the help of this dynamics equation the computer storage is much reduced as compared with other methods in calculation.A numerical example is given.
