柔性传动系统动力学数学模型的转化

Transformation of Dynamic Models in Flexible Transmission System

对三种较为典型的柔性传动系统，先用拉格朗日方程建立动力学数学模型，再选取适当的广义坐标，通过线性变换，得到各集中质量位于同一轴线的等效模型，从而使原模型向实际典型的三类柔性传动系统转化，得到相应柔性传动系统三种动力学数学模型。

Three kinds of typical transmssive systems is obtained in this paper. First, the dynamicmodels is established by Lagrange Equation. The equivalent model is given with each lumpmass located on one axis by linear transformation and proper general axes. Therefore, theoriginal model is transformed to the three kinds of typical flexible transmission systems. Theconvenient conditions are offered for the theoretical analysis and design computations offlexible transmission systems.
