Axial crushing component and collision analysis method of structure having shaft crush component

摘要

The present invention relates to a method of accurately performing collision analysis of a shaft crushing component of an automobile including a press molded product having a flat surface formed with a bead portion and a structure having the shaft crushed component.A collision analysis method of a shaft crushing component according to the present invention and a structure having such a shaft crushed componentThe inner plate 3 and the outer part 5 including the bead part 3A1 and the bead part 5A1 are formed in the top plate part 3a and the top plate part 5a, and the top partCollision analysis of front side member 1 collapsed in axial direction by input of collision load to axial endAn inverse analysis of inner parts 3 and outer parts 5 is performed.The bead part 3A1 and bead part 5A1 and the machining strain distribution around these are calculated.The calculated bead portion 3A1 and bead portion 5A1 and the processed strain distribution around these are mapped to an analysis model of the front side memberThe collision analysis is performed.Diagram
