摘要： The invention provides a component formed of an aluminum alloy for use in a vehicle, for example an automotive vehicle component requiring high strength, light-weight, and a complex three-dimensional shape, and a method of manufacturing the component. The method begins by providing a blank formed of an aluminum alloy which is already solution heat treated and tempered, and thus has a temper designation of about T4. The method further includes heating the blank to a temperature of 150° C. to 350° C., preferably 190° C. to 225° C. The method next includes quickly transferring the blank to a hot or warm forming apparatus, and stamping the blank to form the complex three-dimensional shape. Immediately after the forming step, the component has a temper designation of about T6, but preferably not greater than T6, and thus is ready for use in the vehicle without any post heat treatment or machining.

摘要： A cooling plate assembly for cooling at least one battery module in a battery tray includes a first plate and a second plate disposed in stacked relationship with one another to collectively define a cooling channel extending therebetween. An adhesive is disposed between the first and second plate and extends along at least a portion of the cooling channel for structurally bonding the first and second plates to one another. At least one mechanical fixation is disposed adjacent the adhesive and extends between the first and second plates for maintaining a position of the first and second plates during a curing of the adhesive. A method of manufacturing the cooling plate assembly is also disclosed.

摘要： A system and method for an improved material flow through an extrusion machine by altering the material properties in a magnetic field are provided. The electromagnetic extrusion system includes a ram that is moved into a chamber containing an extrusion material to force the extrusion material out of an opening defined, at least in part, by a die to create an extrusion with a cross-sectional shape corresponding to the predetermined shape of the opening. An electromagnetic winding of electrically conductive material is embedded within a tool retainer block surrounding the container and is helically wound about the chamber and carries a DC electrical current to generate a magnetic field having a magnetic flux density of at least 2 Tesla within the extrusion material to dissipate dislocation defect structures in the extrusion material being extruded via the magnetoplasticity effect. The magnetic field therefore provides for reduced flow stress on the tooling.

摘要： A weld quality inspection system for indicating a quality of a weld during a welding process on at least one work piece. The weld quality inspection system includes an infrared camera configured to provide visual data of a weld pool. A microphone is configured to provide audio data of an arc of a welder. At least one operational technology (OT) data source is configured to provide OT data. A controller is configured to receive the visual data, the sound data and the OT data to determine if conditions associated with a bad weld are met and to provide feedback to an operator or robot in response to a detection that the conditions are met.

摘要： An automatic system (10) and method for efficiently cleaning grease and debris from a die (12) is provided, for example, a die (12) which stamps or trims aluminum or steel sheets used to form exterior vehicle body panels and thus should be free of dents and scratches. The system (10) includes multiple stations (22) and die handling arms (18), (20) or a conveyor (28) for moving the die (12) between the multiple stations (22). One of the stations (22) includes a spraying device (26) for cleaning and rinsing the die (12). Another one of the stations (22) includes an air blower (24) for removing loose debris from the die (10) and also for drying the die (10) after the washing step.

摘要： A vehicle door system includes a door with a door module and a hinge module. The hinge module is attached to the vehicle body. The door module is attached to the hinge module. The hinge module includes a hinge bracket attached to the vehicle body, and a pair of arms extending from the hinge bracket that can pivot relative to the hinge bracket and a cross brace attached at the ends of the arms. The door module attaches to the cross brace. The door module moves along with the cross brace, which moves along with the arms as they pivot relative to the hinge bracket. The door module includes a latch mechanism at a bottom edge, with the latch mechanism engaging with the vehicle body. A lateral edge of the door may seal against a lateral edge of the second door without a latch interface.

摘要： A switching circuit of a motor drive includes a high-side switch configured to selectively conduct current between a DC positive conductor and an output conductor, and a low-side switch configured to selectively conduct current between the output conductor and a DC negative conductor. The high-side switch comprises a depletion mode (D-Mode) gallium nitride (GaN) high-electron-mobility transistor (HEMT) and a Si-FET in a cascaded configuration, and the low-side switch comprises a D-Mode GaN HEMT. This arrangement can provide a safe state operation in which the switching circuit provides a default condition providing electrical continuity between the DC negative conductor and the output conductor and providing electrical isolation between the DC positive conductor and the output conductor in the event of a loss of control signals.

摘要： A structural component for a vehicle may include an extrusion that is extruded into a first state and then expanded into a second state. The extrusion in the first state has a reduced size relative to a desired final size. The extrusion in the first state is placed within a die that defines the desired final size. Pressurized water is distributed within internal cells of the extrusion in the first state such that the walls defining the internal cells are expanded into engagement with the surface of the die, thereby creating surface features or sealing interfaces with tight tolerances. The relative shape of the die and the extrusion in the first state defines an open space herebetween, into which the extrusion may expand to define the final shape. Some of the internal cells may be plugged such that they are not provided with pressurized water.
