摘要： A thin-skin support member is provided. The thin-skin support member may include a semi-circular edge (308) and a flat edge that define a hollow cavity (200). A cylindrical cavity (300) may be adjacent the hollow cavity and at least partially defined by the semi-circular edge. The cylindrical cavity may be configured to retain a strut assembly. A mounting interface (112) may be coupled to the semi-circular edge and the flat edge. A torsion interface may be disposed adjacent the cylindrical cavity and configured to receive a torsion link (116, 118). The thin-skin support member may be made using additive manufacturing and thus may have a grain structure grown in the direction of material being added.

摘要： A hot-pressed member is formed using a tailored blank material obtained by butt joining respective ends of two or more coated steel sheets. The hot-pressed member has two or more sites formed by the respective coated steel sheets and at least one joining portion between the sites. Depending on a type of a coated layer of each of the coated steel sheets, t w /t 0 is appropriately controlled where t w is a thickness of a thinnest portion in the joining portion and t 0 is a thickness of a thinnest site of the sites. A tensile strength of each of the sites is 1180 MPa or more.
