Simulation analysis and application of multi-step stamping process for automobile crossbeam
In order to study the influence of multi-step stamping forming CAD/CAE technology on the forming per-formance of body structural parts,the blank layout design,positioning design of process parts,and full-process stamping forming simulation of the automobile crossbeam were carried out by comprehensive use of UG software and AutoForm software.The results show that the 12-step layout can meet the multi-step stamping requirements of the parts;The finite element simulation of the whole process is carried out for the process obtained after removing the corresponding process of the virtual material removal process,and the qualified analysis results are obtained;The in-spection tool and three-dimensional coordinate measuring machine were used to detect the actual punching product parts in turn,reflecting that the shape accuracy of the parts met the assembly requirements,and the dimensional de-viation of the key parts basically met the requirements.
