TLDR
In this paper, a vehicle space frame is built up piece by piece into an initial or rough frame, consisting of standard, cylindrical metal tubes welded to matching cylinders of hollow, nodal joints.Abstract:
A vehicle space frame is built up piece by piece into an initial or rough frame, consisting of standard, cylindrical metal tubes welded to matching cylindrical plugs of hollow, nodal joints. All weld seams are circular and, therefore, easily and quickly formed, and the initial frame need be formed only with the accuracy that plugging the ends of the tubes into the joints will achieve. The entire interior of the initial frame is then clamped between a large pair of dies with mating cavities, and hydroformed to provide a final frame with the desired non cylindrical cross section and accurate, final shape and form.read more

Hydroformed space frame and method of manufacturing the same
TL;DR: In this article, a space for a motor vehicle comprising a first hydroformed, longitudinally extending tubular lower side rail (12) and a second, generally parallel, hydroformed tubular upper longitudinal structures (20), each being an integrally formed structure fixed to an associated one of the lower side rails.

Hydroformed space frame and joints therefor
TL;DR: In this paper, a vehicle space frame joint is formed by forming an elongated first member constructed of a metallic material that includes an end segment having a predetermined length and having an exterior surface that defines an exterior configuration of the end segment.

Heat-activated structural foam reinforced hydroform
TL;DR: In this paper, a reinforced hydroform member (10) having an outer structural member (12) reinforced by a structural foam (16) over an inner structural member is described.
Patent
Hydroformed side rail for a vehicle frame and method of manufacture
TL;DR: In this paper, a vehicle frame side rail is manufactured by prebending a cylindrical tube of constant wall thickness into a shape consistent with the desired final shape, and then hydroforming an intermediate work piece in a first die to provide wall thickness and perimeter characteristics commensurate with the final product.
Patent
Modular space frame
TL;DR: In this paper, a vehicle space frame for constructing a pick-up truck-style motor vehicle includes a body module (30), a front module (22), and a front connecting structure (44).

Hydroforming of compound tubes
TL;DR: In this article, a method for producing a tubular structural member which can longitudinally vary in wall thickness, perimeter and material using the hydroforming process is presented, which is accomplished by first fabricating a tube blank of the desired longitudinal combination of wall thickness and material by welding together portions of tubing having the desired characteristics and then hydroforming the resultant blank.
Patent
Motor vehicle body.
TL;DR: In this paper, a motor vehicle body is assembled from a plurality of metal frame profiles held together by node connector elements, each metal frame profile includes an extruded metal portion and a pre-shaped sheet metal portion attached to form a portion of the outer skin of the completed motor vehicle.
Patent
Method of forming reinforced box-section frame members
TL;DR: In this article, a method of forming hollow, box-section, frame members which include localized reinforcement is described, where the frame members are produced by fitting a sleeve about a tube, deforming the tube and sleeve to avoid the occurrence of frictional drag in a final die, and then expanding the tube to form the hollow box section, frame member.
Patent
External seal unit for tube hydroforming
TL;DR: In this article, the authors describe a sealing device for a hydroforming press, which consists of a cylindrical bearing and an annular seal carrier mounted on the inside of the tube.
