Roll Forming Simulation with LS-DYNA

The FEA (Finite Element Analysis) simulation of the roll forming process needs amazing short calculation time if the proper simulation model (shell or solid) is selected, the proper CPU count is available, and the FEA system is parameterized optimally. The software developers of UBECO succeeded in close collaboration with the FEA specialists of DYNAmore to optimize the system in order to get short calculation time and stable operation.
As an example a bumper profile was used for comparison: The profile was roll formed on a 20 stands roll forming machine by pure bending. Because no massive forming occurs, shells as element models are the number one choice. The table shows the result: Dependent on the count of CPU's (4, 8, 16, or 32) total computation times between 8.5 and 3 hours are achieved. For comparison: If solids are taken as element model and 4 elements are chosen in sheet thickness direction, the total computation time takes between 22 and 8 hours.
Compared with the past, today's times are amazing short. Now it is possible to modify a roll tool set several times, to repeat the FEA simulation by using the time-saving restart at the modified stand, and to optimize the result. Thus the roll tool designer gets the roll tools set that produces the proper profile with the required allowances.

These and more new functions will be shown on the Blechexpo exhibition Nov. 07-10, 2017 in Stuttgart/Germany: Hall 5 Stand 5500, joint stand with DYNAmore. The new release will be available from December 2017. Get more info from: UBECO GmbH, Baarstr. 121, D-58636 Iserlohn, Germany. Phone: +49-2371-9771-0, FAX: +49-2371-45550, E-Mail:
