第六章模态试验的应用6.1引言模态试验有许多方面的应用,第一章中已列举了一些主要的应用例子,本章中我们依次对它们进行讨论,并研究一些有效的方法。但应注意,所述的这些方法应用于实际工程结构时,常常比预料的情况要困难得多,这有许多原因,如在实际情况下,需要大量的数据,而实际数据的不完全性等等。当然也不应失去应用这些方法的信心,它们还是能非常有效地付之应用的。而且随 Chapter Six: Application of Modal Testing 6.1 Introduction Modal testing has many applications. The first chapter lists some major application examples. In this chapter, we discuss them in turn and study some effective methods. However, it should be noted that these methods, when applied to actual engineering structures, are often more difficult to predict than expected, for many reasons, such as the need for large amounts of data in actual situations, the incompleteness of actual data, etc. Wait. Of course, we should not lose confidence in the application of these methods, they can still be very effective application. And with
