摘要
介绍了Lanczos算法的理论,建立细长弹体的有限元模型,将Lanczos法与有限元技术结合,对细长弹体进行模态分析,得出不同时刻三种状态下弹体的前两阶模态,研究结果对细长弹箭的设计具有一定参考价值。
The Lanczos method was introduced. The finite element modeling of slender missile was accomplished. Combining Lanczos algorithm with finite element method(FEM), modal analysis of ,slender missile was made to get natural modes of the first and second order. The results have some reference value for the design of slender missile/rocket.
