摘要
提出了平面运动弹性梁杆系统动力分析的、较为通用的实用方法．按本文方法形成的几何非线性系统平衡方程，具有在所有系数矩阵和荷载列阵中都不含未知变量的二阶导数的特点。
A more universal practical method for dynamic analysis of planemoving elastic beambar systems is put forward. The geometric nonlinear system equilibrium equations formed according to the method have the characteristic that there are no second derivative of unknown variables in any coefficient matrixes or load colum matrix, so they are very easy to be solved.
