导弹舵翼动态特性的数值分析

Numerical Analysis on the Dynamic Characteristics of the Missile Vane

为了研究导弹舵翼的动态特性,文中以一种尺寸的导弹舵翼为例,通过有限元模态分析,得到了舵翼的固有频率及其对应的振型,绘出了舵翼各阶数的模态彩色云图,并进行了扩展模态,其计算结果对舵翼的结构设计及材料的选择具有重要的参考价值,同时也为进一步动力学分析做好了准备。

To research the dynamic characteristics of the missile vane, we selected one kind of geometry missile vane as an example in this paper. Using the finite element modal analysis, we gained the natural frequencies and mode shapes of the missile vane, displayed different ranks contour and expanded the modal. The results have important value to the choice of the missile vane material and its structural design. Meanwhile they make preparations for the dynamical analysis further.
