摘要
本文研究了模态截断情况下,只用保留模态和系统矩阵来计算振型一阶导数的方法。
This paper deals with the method to carry our computaion of the first de-n ation of vibration model for the condition of truncated mode, by means of which the first derivation of vibration model could be obtained just only by using reserved model and system matrixes.
