摘要
研究了适用于自由装填药柱应力分析的有限元方法,并对某型号导弹的固体发动机药柱进行了应力分析及结构完整性分析。
The finite element method adapted to the stress analysis of free loading solid rocket grains is studied. The numerical results about a free loading grain are given by using the finite element method, and the structure integrity of the free loading grain is analyzed.
