本文研究模态分析当中剩余导纳的处理问题。首先引入了几个导参数;利用这几个导纳参数导出了剩余导纳展开式,并从而得到了高阶与低阶剩余模态的一般解析形式;给出了当剩余模态项取展开式的某几项时的误差分析方法。使用本文推荐的模型方程编制的计算机模态识别程序,在实用当中取得了比较满意的结果。 This paper studies modal analysis of the remaining admittance processing problems. Firstly, several guidance parameters are introduced. Based on these admittance parameters, the residual admittance expansion is deduced, and the general analytical forms of the residual modes of higher order and lower order are obtained. Some of the time when the error analysis method. Using the computer model recognition program prepared by the model equation recommended in this paper, we obtained satisfactory results in practice.
