摘　　要：对固体运载火箭在铁路运输过程中出现侧翻异常工况下的安全性进行研究,在调研、分析多种减振吸能方案的基础上,提出了缓冲气囊和蜂窝金属组合的侧翻吸能系统技术方案。采用Hypermesh和LS-DYNA软件进行侧翻仿真计算,结果表明:该方案可将火箭侧翻跌落的加速度由27g降为8.91g,发射筒与车厢的接触碰撞力由382.59kN降为无接触,可明显提高固体运载火箭在铁路运输侧翻等异常工况下的生存能力,为后续固体运载火箭专用铁路车的设计提供重要指导。The safety of solid rocket launch vehicles under the abnormal side tumbling condition in the process of railway transportation is studied.Based on investigation and analysis of various vibration absorption schemes,the technical scheme of energy absorption system with the combination of cushion airbag and honeycomb is put forward.The side-rolling simulation analysis is carried out using Hypermesh and LS-DYNA software.The results show that the acceleration of the rocket's side-rolling down decreases from 27g to 8.91g,and the contact collision force between the launcher and the carriage decreases from 382.59kN to non-contact by using the above technical scheme.Meanwhile,it can obviously improve the safety of solid rocket launch vehicles under abnormal conditions such as railway transport rollover.Finally,it provides important guidance for the design of special solid rocket launch vehicles.
