导弹动态特性数值分析的建模方法研究

The Research of Modeling Methods for A Missile's Dynamic Characteristics Numerical Analysis

文中基于ANSYS软件平台,通过建立合理的有限元模型,对某导弹结构进行了动态特性分析;同时利用等效密度有效地简化模型,为导弹大型有限元模型的模态估计提供了一种简单可行的方法。

This paper based on the platform of ANSYS, by building a reasonable finite-element model, the dynamic characteristics of a missile is simulated. Making use of equivalent density the model is simplified effectively, a simple and feasible method is offered for mode estimation of a missile's large-scale finite-element model.
