本文使用有限元数值仿真方法对某型复合材料发射筒进行水锤动态载荷下结构强度、刚度研究。研究结果表明，主体段采用复合材料，上、下法兰采用铝合金的结构方案，能够满足承载要求。开展部段样机的承载试验，与样机的仿真结果吻合，验证设计结果的正确性，为碳纤维复合材料筒设计提供支撑。
In this paper , the finite element numerical simulation method is used to study the structural strength and stiffness of a composite launcher under the dynamic load of water hammer. The results show that the structure scheme of composite material in the main section and aluminum alloy in the upper and lower flanges can meet the load-bearing requirements. The bearing test of the part prototype is carried out, which is consistent with the simulation results of the prototype, which verifies the correctness of the design results and provides support for the design of the carbon fiber composite cylinder.
