高速飞行体无损回收装置的虚拟设计研究

The Hypothesized Design Research of the Recycling Installment of the High-speed Flight Without Damages

文中以弹道修正或末端制导弹药一类的高速飞行体为对象,研究其试验样机内精密光机电控制器件或微处理部件等在抗高过载实验中,飞行体载体在最大回收减加速度和规定截停距离的限制条件下无损回收的方法问题。在充分分析已有的各种缓冲材料基础上,选取新型的泡沫铝材料为回收介质,采用ANSYS/LS-DYNA有限元分析软件对高速飞行体撞击和侵彻泡沫铝缓冲材料的过程进行了数值仿真分析研究,从而设计出一套密度逐渐增大、多节的回收装置。

This article takes a kind of high-speed flight body such as the ballistic correction or terminal guidance ammunition as objects, studies the method of the precise light mechanical and electrical control components or the micro processing units and so on which are in experimental prototype can be recycled without damages under the limiting condition of the biggest recycling negative acceleration and the certain distance in the anti-high overload experiment. The full analysis of each kind of cushion material, selects the new froth aluminum material as the recycling medium, uses ANSYS/LS- DYNA finite element analysis software to conduct analysis and research on the numerical simulation of the process of the high-speed flight body hitting froth aluminum cushion material,so design a set of multisection recycling system which density is gradually increased.
