METAL STRUCTURAL ELEMENT CONTAINING STRAP WITH INCREASED DUCTILITY, AND METHOD OF MANUFACTURING THEREOF Russian patent published in 2024 - IPC B62D25/04 

FIELD: machine building.

SUBSTANCE: group of inventions relates to the field of transport machine building. Method for manufacturing a metal structural member for a vehicle comprises the following stages: a) preparing a flat workpiece passing in a longitudinal direction and in a first transverse direction; b) cutting a workpiece to form a hole; c) welding the strap to the workpiece to close the hole; d) forming the assembly formed by the workpiece and the strap to obtain an element characterized by the presence of a section with a U-shaped cross section. Metal structural element made using said method is a profile containing a section with a U-shaped cross section. Said section is characterized by the presence of a lower part and two side walls, and is characterized by a longitudinal direction, a first transverse direction and second transverse direction, setting in U-shaped cross section. Automotive vehicle comprises said metal structural element.

EFFECT: improved mechanical reaction of metal structural element to impact action.
