摘要 本文介绍一种有别于模态分析法的直接积分法。介绍了多自由度线性系统运动微分方程化为状态方程的方法．介绍了状态方程的解法以及其离散化后的迭代法，给出了计算框图。 This method deals with direct integration method,which is different from modelanalysis method. This paper presents a method of turning motion differential equationinto state equation in multiple freedom degree linear system,introduces a method ofsolving state eguation and its discretization iterative method,offers its calculating blockdiagram too.
