A front side member configured to be supported by a vehicle frame includes a tubular body formed of a roll-formed high strength metal and configured to withstand an axial load during a front collision of the vehicle. The high strength metal sheet defines a cross-sectional shape along the length of the tubular body. The tubular body includes a central wall extending from a first side wall to a second side wall defining at least a first longitudinal channel and a second longitudinal channel. A groove is disposed in the first sidewall of the tubular body and extends longitudinally along at least a portion of the length of the tubular body to reinforce the tubular body. A bore extends through the first sidewall of the tubular body proximate the groove, and is configured as a bend initiator.

    一种被构造成由车辆车架支撑的前纵梁包括管状主体,所述管状主体由滚压成型的高强度金属形成并被构造成在车辆前部碰撞期间承受轴向载荷。高强度金属板沿所述管状主体的长度限定横截面形状。所述管状主体包括中心壁,所述中心壁从第一侧壁延伸至第二侧壁,从而限定至少第一纵向通道和第二纵向通道。凹槽设置在所述管状主体的第一侧壁中并沿所述管状主体的所述长度的至少一部分纵向延伸,以加强所述管状主体。孔延伸穿过所述管状主体的所述第一侧壁,靠近所述凹槽,并且被构造为弯曲引发器。
