§5.0 概述到目前为止,我们已讨论了模态分析的各种主要方法。现在,我们来研究如何利用它们达到开始的目标,即建立被试结构的数学模型。在回顾本书的前几章时,我们不难发现:把要构造的数学模型分为几类,并研究这些模型的不同应用场合是很方便的。本学科的内容相当广泛,没有一个单一的模型能适用于所有的情况。因此,测试和分析步骤的具体结合要根据应用情况而变化。我们就得到模型化过程的最重要方面:在开始采集和处理实验数据以 §5.0 Overview So far, we have discussed various major methods of modal analysis. Now, we will study how to use them to achieve the initial goal of establishing a mathematical model of the structure being tested. In reviewing the first few chapters of the book, it is not difficult to find that it is convenient to divide the mathematical models to be constructed into several categories and to study the different applications of these models. The content of this subject is quite extensive, and no single model can be applied to all situations. Therefore, the specific combination of test and analysis steps will vary depending on the application. We get the most important aspect of the modeling process: we start collecting and processing experimental data
