Expert in tube mills upgrades finite element analysis system

PUBLISHED: 06 Nov 08

Roll-Kraft, USA, has upgraded its system for finite element analysis, in response to increased demand for such services from both the rollforming and tubing industries. The update includes the integration of a new, high-performance, dual-processor computer.

Upgrading the Copra RF FEA software from Data M Software is designed to take advantage of the new computing power.

The new release of the FEA software has increased functionality. An engineer can designate which roll passes are driven and non-driven, as well as define the line speed and account for friction in the tooling. The program is also able to simulate nonsymmetrical, formed-up welded profiles.

Early tests have resulted in a calculation time reduction of approximately 75 per cent, compared to the previous FEA system. The increased capacity will allow Roll-Kraft to use the FEA more effectively during the design phase of the project.

The improvements in both speed and functionality will benefit customers in several ways. The decrease in calculation time will permit the running of more simulations of various tooling design concepts during the engineering phase, in order to develop the best possible solution for producing an accurate profile. This will, in turn, decrease the amount of time a set of tooling spends in the testing phase. The addition of the rotating rolls, line speed, and friction functions will better allow the prediction of possible surface condition problems in the finished product.

With many industries switching to lighter, stronger materials and more complex profiles, the need for a scientific approach to tooling design has become necessary. Roll-Kraft often uses the FEA system in an R&D role, and collaborates with existing and potential customers to determine the feasibility of rollforming these advanced materials and products.
