本文提出了二次矩阵特征值问题的一种改进的有效算法。文中,利用本算法计算了双层空间框架的模态特性,并与文献[3]中的算法和实验值进行比较。结果表明,本算法是很有效的。
In this paper, an improved and efficient algorithm for the eigenvalue problem of quadratic matrices is proposed. In this paper, the modal properties of the double space frame are calculated by this algorithm and compared with the algorithm and experimental data in [3]. The results show that this algorithm is very effective.
