火箭弹稳定装置强度有限元分析

稳定装置是火箭弹的重要部件,它在火箭弹飞行中产生升力,能使火箭弹维持良好的稳定性,如果稳定装置在飞行的过程中发生失效,火箭弹会丧失稳定性,甚至发生掉弹现象.因此研究稳定装置的强度具有重要的意义.利用SolidWorks建立了火箭弹尾翼装置实体模型,然后导入ANSYS中对稳定装置建立有限元计算模型,进行了尾翼强度的有限元分析,得出翼片、尾翼筒、支耳应力、位移云图与材料强度要求进行对比.

The strength finite element analysis of rocket stability unit

Stable equipment is an important part of rockets,rocket-propelled grenade in flight it produces lift,makes the rocket to maintain good stability,if stable device in flight during failure,rocket would lose stability,even off-phenomenon.As a result of stability unit strength has important implications.This article use SolidWorks has established a solid model rocket tail unit,and then import the ANSYS establishment of stable unit in finite element calculation model,is the tail of the finite element analysis,came to the fins and tail cone and ear stress,displacement map and material strength requirements.
