摘要
以防空导弹大长径比双推力固体火箭发动机装药为研究对象,分析了导弹旋转发射出筒过程中承受的各类载荷。通过计算装药的应力—应变场,发现了装药的危险部位,进而分析了燃烧室发生高压爆炸原因。
A kind of anti-aircraft missile solid rocket motor with high length-diameter ratio was taken as the ob- ject of study, all kinds of load on the grain during the process of the missile rotary launching out of the con- tainer was analyzed in detail. By computing the stress-strain field of the grain, the danger part of the grain was found, and the cause of the combust chamber high pressure explosion was analyzed.
