Flange wrinkling in incremental shape rolling

چکیده
Abstract. Automotive structural components from Advanced High Strength Steels (AHSS) can be manufactured with Flexible Roll Forming (FRF). Flange wrinkling is a common shape defect in FRF, this restricts the application of FRF automotive industry. The new Incremental Shape Rolling process (ISR) showed that high tensile transverse strain developed flange and assists plastic deformation flange. Hence, wrinkle severity significantly reduced when weight-optimized are formed. In study, ISR applied to variable width profile DP600. This investigated modified component. forming strains compared those obtained case. experimental trials performed on prototype facility then used validate numerical models which analyse behaviour both processes. results show significant reduction wrinkling. due facilitates hence stably compressed required shape.

A CLOSED-FORM NON- LINEAR SOLUTION FOR PLASTIC FLANGE WRINKLING OF CIRCULAR PLATES IN DEEP DRAWING PROCESS
This paper deals with two-dimensional plane stress wrinkling model of a plastic annular plate. Based on energy method and the nonlinearity of strain-displacement law, a bifurcation function in polar coordinates is derived analytically. This technique leads to the critical conditions for the onset of the plastic wrinkling of flange during the deep drawing process. To find this solution, the Tres...

متن کاملIncremental Support Vector Regression for Steering Hot Rolling Mills
Machine learning concepts, such as the support vector machine (SVM), have been theoretically discussed in great detail, but in industrial applications still rather old-fashioned solutions are preferred. To show that learning concepts improve industrial planning, scheduling, and steering processes, a cooperation with a steel manufacturer was initiated to build a prototype pass schedule calculato...
