Effect of Deformation Mode of Cylindrical Tubes with Corrugated Surface Dimensional Errors

摘要：

A cylindrical tube with a corrugated surface in the axial direction has excellent energy absorption characteristics as an automobile impact-absorbing part. In this paper, the difference in the deformation mode between the analysis results using a finite element method (FEM) and the experimental results obtained using actual cylindrical tubes is investigated. It is shown that the difference is caused by initial irregularities such as size errors. Furthermore, it can be denoted that the loaddisplacement curve and the deformation diagram are good agreement in the S-mode. However, there is a difference in the deformation diagram and a slight shift in the load-displacement curve in the P-mode.
