Effect of Rigidity of Strut on Crashworthiness of Civil Aircraft

  • 摘要: 针对某小型民机典型机身段,采用对货舱支柱结构预制缺口的措施实现支柱压缩刚度的改变。运用HyperMesh软件建立3种不同刚度支柱的3框段机身结构有限元模型,应用LS-Dyna有限元软件对模型进行了坠撞仿真,对比分析在垂直坠撞速度为7m/s时,3种机身段的变形模式、吸能模式、速度时间历程曲线和加速度时间历程曲线。结果表明,在坠撞过程中,支柱刚度过大或过小均会对乘员的生存带来严重威胁,对支柱进行合理的缺口预制可有效控制机身段变形模式,改善飞机抗坠撞性能。
