摘要
本文使用有限元数值仿真方法对某型使用碳纤维复合材料替代高强度铝合金材料的发射筒进行内压工况下结构强度、刚度研究。研究结果表明,当前结构下,高强度铝合金筒与碳纤维复合材料筒最大结构变形相当时,结构应力均小于材料许用应力,且碳纤维复合材料筒重量比高强度铝合金筒轻48.64%。研究结果可为发射筒使用碳纤维复合材料替代金属材料的方案设计提供参考。
In this paper,the finite element numerical simulation method is used to study the structural strength and stiffness of a launch tube using carbon fiber composite instead of high-strength aluminum alloy under internal pressure.The research results show that under the current structure,when the maximum structural deformation of the high-strength aluminum alloy tube and the carbon fiber composite tube is equivalent,the structural stress is less than the allowable stress of the material,and the carbon fiber composite tube is 48.64%lighter than the high-strength aluminum alloy tube.The research results provide a reference for the design of the emitter using carbon fiber composite instead if metal.
