In the introductory part, various types of automotive suspension systems and their operation are presented, with special emphasis on the sheet metal design. The main problem addressed in this thesis arises from the stress states that occur in the control arm during actual driving, which are the result of both dynamic forces and residual stresses caused by mechanical
forming during manufacturing. The following section includes an analytical calculation of longitudinal, lateral, and vertical forces under different driving scenarios (braking, driving over an obstacle, cornering), followed by a computational simulation in the Ansys software environment. Eight load combinations were analyzed in the simulations, each evaluated
twice – once without and once with consideration of residual stresses. The results showed that the presence of residual stresses significantly affects the stress distribution in the component, especially near mounting points. Critical areas are clearly expressed in combinations involving heavy braking and driving over larger obstacles in corners, which is crucial for further optimization of the structure.
