特种低温内压筒体抗冲击设计

SHOCK RESISTANT DESIGN OF SPECIAL CRYOGENIC INNER PRESSURE VESSEL

用有限元方法计算了低温液氧储槽内筒在３９２ Ｍ Ｐａ、１０ ｇ 冲击条件下的应力分布情况，

The inner container stress distribution of a cryogenic liquid oxygen vessel is calculated with finite element methods under the condition of the high inner pressure and the strong collision,and the inner container strength with reasonable structure is verifide with analytical design method.The conclusion isdrawn that the reinforced plate structure of the inner container is safe and reliable under the condition above.
