Structural Optimum Design and Pre-stress Simulation of Fiber Housing for Railgun

  • 摘要: 介绍了电磁轨道炮复合身管纤维缠绕封装的结构优化设计方法。给出了∅50 mm复合身管纤维层的缠绕厚度、缠绕角、层叠次序优化结果。基于生死单元及多步连续降温,给出了缠绕增强复合身管的预应力逐层模拟方法。采用分步逐层随机搜索法,优化了纤维缠绕张力制度,详细分析了两种状态约束下的张力优化结果,并给出了对应的身管初应力场和发射叠加应力场。优化结果表明,Ⅱ型张力方案中身管复合层发射前及发射过程的应力分布满足身管预应力设计要求。
