介绍了应用传递矩阵法求解轴系的固有频率和主振型,轴系模型及其参数的识别。以及传递矩阵的计算机方法,不仅简便易行,而且计算精度较高,能为轴系动态设计提供可靠的参数,具有较高的适用推广价值。

In the design of axis system,the research of dynamic characteristic is important and especially the calcution of natural frequency and principal modi are very important. Usually in using the method of the analysis of the simulated state, axis system to be simplified into the mechanical model of more degree of freedom which causes the number of equation to increase, raises the order of matrix of the calculation and increase a lot of work, so it has many disadvantages. This article introduces the method of the transition matrix which is used to solve the natural frequency and axis system. It also introduces the way to distinguish the model and parameter in axis system as Well as the way of computer of the transition matrix is not only easy to use but also very accurate to calculate. It can provide reliable parameter of natural vibrition for the design of dynamics in axis system. It has a high value of the use and popularization.
