Title Hydroforming finite element analysis and technical study of Cone-bottom box
Abstract
Cone-bottom box is non-rotating curved-surface box,belongs to non straight-wall shaped-parts.When it is hydroformed,the sidewall is easy to wrinkle,and everywhere around the box is easy to be deformed nonuniformly.By hydroforming finite element analysis, simulative forming for the box was carried,,and appropriate parameters was seeked for, surface forming quality was optimized,the generation of the problems above was controled.
Deforming law of the cone-bottom box was analyzed and the problems easily exposed at the time of deforming was studied.When the deforming was being discussed,firstly,the box mould was modeled by PRO/E;next its hydroforming process was finite element analysed by Dynaform,the influence to the hydroforming process by different mould parameters, different friction factors, feeds and the type and amount of hydraulic pressure was discussed;finally,in the study,the most optimal option was obtained by orthogonal test.the effective solution on hydroforming process was proposed,and the realistic meaning and foreground of this task were discussed in the papers.
Keywords：hydroforming Cone-bottom box Dyanform orthogonal test
