摘要:
为保持巡航状态飞艇头部气动外形,有效减小艇体表面应力集中,提升艇首抗褶皱能力,同时满足重量、刚强度及环境适应性要求,设计了一种全包围式变截面飞艇鼻锥结构。利用轻量化设计原理,此鼻锥采用薄壁一体化芯轴组件+变截面腹板式铆接骨架的主体结构形式,鼻锥根部与艇体连接采用管状桁条连接结构; 同时,借助ABAQUS软件对极限载荷工况下的鼻锥结构进行有限元分析,计算结果显示强度和刚度均满足设计要求,鼻锥主体重13 kg,轻量化率85%,经试验表明,此鼻锥结构稳定可靠,对类似飞艇鼻锥结构设计具有重要参考意义。
Abstract:
In order to maintain the aerodynamic shape of cruise airship head and meet the requirements of weight for reducing the hull surface stress concentration effectively and improving pudding fold resistance, a whole-surround and variable cross-section nose structure was proposed. Using the lightweight design principle, the nose structure was designed with integration of thin walled core shaft components and variable cross-section web type, the nose root was connected to the hull structure of tubular purlin connection. The nose structure of limit load working conditions was analyzed with the help of ABAQUS software. The calculation results show that the strength and stiffness meet the design requirements. The weight of nose structure is 13 kg, with the weight reduction rate of 85%. The analysis show that the structure is stable and reliable by testing, which provide important reference significance for similar airship nose structure.
