摘要

为提升布撒器抛撒气囊的承压强度及抗氧化能力,提出一种薄壁金属气囊的设计方案。通过无距理论得到不锈钢金属气囊的壁厚。依据金属气囊的结构特性,设计焊接夹具和工艺。同时采用Rosenthal移动线热源模型,计算焊接过程的温度场,得到焊接参数。通过与传统橡胶/芳纶气囊对比分析。结果表明:金属气囊的质量可降低45%,承压强度是橡胶/芳纶气囊的1.5倍,可很好完成子弹药的抛撒任务。
        To improve the bearing strength and the antioxidant ability of the gasbag,a design scheme of thin-walled metal gasbag was proposed. The wall thickness of stainless steel metal gasbag was obtained by the non-distance theory. According to the structural characteristics of metal gasbag,the welding fixture and the welding process were designed. Meanwhile,Rosenthal moving line heat source model was used to calculate the temperature field of the welding process,and the welding parameters were obtained. Compared with the traditional Rubber/Kevlar gasbag,the results show that the weight of the metal gasbag is nearly 45% lighter,and the bearing strength is 1.5 times that of the Rubber/Kevlar gasbag. The metal gasbag can complete the dispersing task well.
