摘要:
An apparatus includes a vehicle structure, a bumper, an elongate structural member, and an extension portion. The elongate structural member is able to crush longitudinally in response to application of force in a longitudinal direction. The extension portion is able to crush longitudinally in response to application of force in the longitudinal direction, is connected to the elongate structural member such that the elongate structural member and the extension portion support the bumper with respect to the vehicle structure, and is operable to move the bumper between an extended position and a retracted position with respect to the vehicle structure to change a distance between the bumper and the vehicle structure.

An extended impingement cooling structure to cool outside an air supply plenum comprises an inner wall; an impingement sheet; a series of supports to maintain the inner wall in spaced relation to the impingement sheet, and a baffle supported between the inner wall and the impingement sheet. The baffle has a collector plenum area that receives impingement cooling air from the air supply plenum and a channel in fluid communication with the collector plenum and extending outside the air supply plenum with openings to allow impingement cooling air to pass therethrough and having a series of lands extending into the channel wherein the lands are located in proximity to impingement cooling air outlets in the inner wall.
摘要:
One embodiment includes providing a contiguous tubular member including at least one of a first material or a second material, so that the tubular member has a wall thickness that varies along the length of the tubular member; bending the tubular member; and hydroforming the tubular member into a part.

A method includes acquiring a first structural component conforming to a design, producing a first vehicle including the first structural component, and transferring possession of the first vehicle with the first structural component having a first set of mechanical properties. The method further includes acquiring a second structural component conforming to the design, subjecting the second structural component to a heat treatment process so that the second structural component is characterized by a second set of mechanical properties different from the first set of mechanical properties, producing a second vehicle including the second structural component, and transferring possession of the second vehicle with the second structural component having the second set of mechanical properties.

Reconfigurable bins include at least one structural component formed of shape memory materials such as a shape memory polymer, a shape memory alloy, or a combination thereof. The shape memory material is in operative communication with an activation device adapted to provide an activation signal effective to change at least one attribute of the shape memory material such that the bin can be reconfigured from a first shape to a second shape. The reconfigurable bin can include a mesh network or may be formed of panels or a combination panels and mesh.
