Summary
The transverse point mobility for a straight spot welded box beam loaded with a transverse end force is calculated numerically by use of the FE-code ABAQUS. The influence of the residual stress field caused by the spot welding and (approximately) by the cold forming on the harmonic response is studied in particular. The residual deformations and stresses caused by the spot welding are estimated using a simplified approach (employing FEM) where the temperature field present during welding is not modelled in detail. This approach is calibrated against calculated results from a detailed 3D-analysis of welding of one spot. The lowest eigenfrequencies of the box beam are found to decrease about 10 % when residual stresses from the manufacturing processes are considered.
