摘要： A vehicle beam assembly includes a hollow tubular member configured to be formed with steel tube air forming. The tubular member includes a varied cross section along a length of the tubular member. For example, the hollow tubular member includes a center portion having a first cross-sectional shape, a pair of end portions that extend past corresponding crush cans in a direction away from the center portion, where the pair of end portions extend at an angle of 40-70 degrees, and at least one transition portion disposed between the center portion and one of the pair of end portions. A cross-sectional shape of the center portion, a cross sectional shape of one of the end portions, and a cross-sectional shape of the transition portion are all different cross-sectional shapes.
