## Analysis of Diamond-Patterned Origami Tubes Under Axial Crushing Forces

• 摘要: 为了降低薄壁管状结构受轴向冲击时的初始峰值载荷，将diamond刚性折纸模型引入到薄壁管状结构的设计中.利用有限元分析方法，以方形截面为例，分析了diamond折纸管状结构的轴向冲击性能.结果表明：相比于传统方形薄壁管，diamond折纸管状结构具有较低的初始峰值载荷和更加平稳的变形过程.得出了diamond折纸管状结构按折纸预折形式变形的临界条件.分析了diamond折纸管状结构在轴向冲击载荷作用下，底角对初始峰值载荷和平均冲击载荷的影响.
