Short summary
The ambition to save weight could be satisfied by adaptation of additive manufacturing. A mild steel powder was validated for dynamically loaded damper brackets for a high-speed train. For mechanical values and dynamic load, conformity could be confirmed. To meet the expectations in static and dynamic load cases, the team has used mature software tools for design and optimization.
