本文从基本元素出发,引述了传递矩阵法的概念,以具体例子说明传递矩阵法在离散振动系统及连续弹性振动系统求解系统固有特性方面的应用.这种方法概念清晰,层次分明,是研究振动系统固有特性的一种新方法。在进行复杂系统的振动分析时,最近迅速发展起来一种新的方法,称为传递矩阵法。这种方法是把复杂的线弹性系统象有限元法那样分割为苦干个元素,各元素之间的特性用矩阵表示,然后把各元素特性的矩阵相乘,就得出整个系统的矩阵,再利用边界条件,可以得到系统的振动特性.所以传递矩阵法是用矩阵的形式,在机器或系统上实现计算程序的一种方法。这种方法编制程序容易,应用范围广泛。
This paper starts from the basic elements and introduces the concept of transfer matrix method to illustrate the application of transfer matrix method in the discrete vibration system and the continuous elastic vibration system to solve the inherent characteristics of the system.This method is clear in concept and distinct in hierarchy, A New Method of System Inherent Features. In the vibration analysis of complex systems, a new method has been rapidly developed recently, called the transfer matrix method. In this method, the complex linear elastic system is divided into several elements as the finite element method, and the characteristics of each element are represented by a matrix. Then, the matrix of each element characteristic is multiplied to obtain the matrix of the entire system, By using the boundary conditions, the vibration characteristics of the system can be obtained, so the transfer matrix method is a method of computing programs on a machine or system in the form of a matrix. This method is easy to program, a wide range of applications.
