本文第一部分介绍一种比较简单的静力凝聚方法。它能对未知变量自动进行分组,而不是对体系进行凝聚划分,无需对凝聚运算准备数据和信息,因而程序的通用性较强。这一部分的末尾附有框图和数例。 第二部分主要讨论动力凝聚。所提出的方法是将凝聚后的非线性缩减方程(已考虑惯性力的影响)转化为一个形式上的线性方程,从而能够应用一般计算方法提取特征值,而且有较高的精度。
The first part of this paper describes a relatively simple method of static aggregation. It can automatically group unknown variables, rather than aggregating the system, and does not need to prepare data and information for condensed operations. Therefore, the program is more versatile. At the end of this section is a block diagram and a few examples. The second part mainly discusses power condensation. The proposed method converts the condensed nonlinear reduction equation (which has considered the influence of the inertial force) into a formal linear equation, so that the general calculation method can be used to extract the eigenvalues with higher accuracy.
