Abstract: A computer-implemented method for simulating and designing a support structure (2) for assembling or gaging a sheet metal part (1) comprises, in a simulation of the sheet metal part (1) and support structure (2), designing a selection of support elements (3) and a position and orientation of the support elements (3) by displaying a computer based visual representation (5) of the sheet metal part (1) to a user. According to a user input, support elements (3) are placed relative to the sheet metal part (1). The method further comprises automatically determining a stability status indicating whether the sheet metal part (1) is stably held by the support elements (3), and displaying the stability status to the user.

Abstract: A computer-implemented method serves for simulating and analysing an assembly of two or more formed sheet metal parts. It comprises simulating a forming process of each part by an approximate simulation (20), and then performing an assembly simulation (40). In order to allow for a quick iteration over different part geometries to assess the assembly, the approximate simulation (20) comprises based on a reference geometry (10) of each part, estimating the deformation of a sheet metal blank required to attain the reference geometry (10); based on this deformation, estimating stresses within the material of the formed part; based on these stresses, estimating the shape of the formed part in which these stresses are in equilibrium, and using this shape as result (31) of the approximate simulation.
