摘要

本文介绍了不同冲击角（0°、10°、20°、30°）下沥青圆柱管的压碎分析。采用有限元分析方法确定了双圆柱管的数值解。此外，质量块作为冲击器在管道的纵向方向上冲击结构。利用非线性有限元软件，随着载荷角和管尺寸的变化，建立了结构的有限元模型。峰值巡航力（PCF）、能量吸收（EA）和比能量吸收（SEA）等参数是本研究的结果，因此可以预期该管是一个很好的能量吸收器。

Finite element analysis of the foam-filled bitubal circular tube under multi-impact loading

Crush analysis of bitubal cylindrical tubes under different impact angles (0°, 10°, 20°, 30°) is described in this paper. Finite element analysis (FEA) was used to determine numerical solution of double cylindrical tubes. Moreover, mass block as impactor impacted the structure in longitudinal direction of the tubes. With variations of load angle and dimensions of tube, a model of structure was developed by non-linear FEA software. The parameters such as the peak cruising force (PCF), energy absorption (EA) and specific energy absorption (SEA) are the outcomes of this study, thus it can be expected that this tube is the great energy absorber.
