发射井内弹-筒系统抗爆减震设计

为提高井下冷发射导弹的生存能力，对其开展了抗爆减震设计研究，建立了弹-筒系统在不同减震方式下的有限元仿真模型，计算了弹-筒系统在爆炸地冲击作用下的动态响应，比较了悬吊式、下支承式、斜吊式等多种减震系统的减震效果，并分析了减震器刚度和阻尼对减震效果的影响。结果表明：悬吊式减震系统的减震效果略好于下支承式，斜吊式最差，合理减小减震器刚度和阻尼可以明显提升悬吊式减震系统的减震效果。

Blast resistant and shock absorption design for missile-canister system in silo

To improve the survival ability of cold launch missile in silo, the research on blast resistant and shock absorption design had been performed. Finite element models were established for missile-canister system in different shock absorption ways. The dynamic responses under blast-induced ground shock were calculated. The vibration reducing performances of several shock absorption systems were compared, including vertical suspension mode, lower supporting mode and slant suspension mode. Meanwhile, the influences of stiffness and damping on the shock absorbing performance were investigated. The results show that the vibration reducing performance of vertical suspension mode is slightly better than that of lower supporting mode, and that of slant suspension mode is worst. The vibration reducing performance of vertical suspension shock absorption system can be significantly improved by properly decreasing its stiffness and damping.
