Accurate Simulation of Tailor-Welded-Blanks to Reduce Process Design Time for the Sheet Pressing Industry

Objetivo

The main objective of the SIM-TWB project is to improve the design and manufacture of tailor-welded blank (TWB) components by using accurate numerical simulation and concurrent engineering methodologies. The sheet pressing operations of tailor-welded blanks will be predicted and optimised via simulation so that a viable product and process design is obtained before costly physical prototyping begins. However, in order to successfully use these methodologies it is key to carry out an accurate modelling of the weld seam including the effects of different sheet alignment, type of welding, heat affected zone and the sheet materials. User-friendliness of the new functionality will be an important consideration in an effort to reduce engineer time in defining simulations. This will optimise components as well as the manufacturing process thus enabling tailor-blanks of higher quality to be produced using curved weld lines, new welding techniques, different sheet alignments and high-performance materials not previously considered. Companies benefit since this significantly reduces costs and improves time-to-market and competitiveness. Users benefit since this reduces vehicle weight and fuel consumption while improving safety and environmental concerns.
Both experimental and computer modelling will be carried out on new technologies to utilise tailor-welded blanks in the automotive industry that is looking at novel ways of reducing vehicle weight. The work will study recently developed welding techniques such as diode laser and friction stir welding to enable the use of high-performance steels and aluminium for tailor-blanks and will look at novel ways of enhancing pressing techniques in order to provide the sector with new technology in this competitive field.
