Crashworthiness of Polygonal Rotary Splicing Origami Tubes Under Oblique Low-Speed Impact Loads
-
摘要:
为提升车用碰撞盒斜向冲击载荷下耐撞性能，该文创新设计出了一种具有多边形旋转拼接折纸图案的折纸管构型，开展了落锤冲击试验及数值仿真分析.研究发现，冲击载荷下新型折纸管较传统方管具有优异的耐撞性，且最终产生具有高耐撞性能的钻石模式.另外，该文对新型折纸管开展了不同冲击角度下几何参数耐撞性影响研究，数值结果表明，新型折纸管折痕高度比和折痕长度比以及宽厚比的参数变化显著影响折纸管耐撞性，并引发不同变形模式；不同冲击角度下，新型折纸管的平均力Fave和峰值力Fmax虽然随着冲击角度θ的增大而逐渐下降，但峰值力Fmax的下降趋势较平均力Fave下降趋势更为显著，且折纸管在不同冲击角度下依旧表现出较高的载荷压溃率ηCFE.进一步验证了多边形旋转拼接折纸管具有优异的斜向冲击吸能性能.
