摘要： A system and method for inspecting an assembly including components joined by self-piercing rivets by a computerized tomography (CT) scan of the joint is provided. The system includes a source of x-rays, a mounting unit for an assembly including the joint which is subject to the x-rays, and an x-ray detector disposed opposite the source for detecting the x-rays. The x-rays are provided at a high energy level of at least 200 kV to generate images having a resolution of at least 200 micrometers (μm). A computer stitches the images together to form reconstructive images which show details of the joint. The assembly to be inspected is not destroyed or modified prior to the inspection process. The resolution of the images generated by the x-rays is high enough to determine the presence of cracks, if any, the interlock (SH), minimum thickness (Tmin), and overall structure of the unmodified assembly.

摘要： An automated inspection system comprises a camera configured to capture an image of a subject item, and a processor in communication with the camera and programmed to recognize the subject item in the image. The processor is configured to determine, from the image, the presence, location, or other properties of a feature of the subject item. The processor may present an augmented reality display as an overlay onto a live image of the subject item. The system may include a portable computing device including the camera and a display screen presenting the augmented reality display with one or more overlays onto a live image of the subject item. The overlays may include icons indicating a feature being recognized as being present and non-defective, or an error icon indicating a missing or defective feature. The portable computing device may include an internal illuminator and/or an external illuminator.

摘要： A cradle for being used in automotive vehicles for supporting various automotive components includes a structure with variable thickness, defining a variable gauge cradle. The variable gauge cradle has a minimum thickness and maximum thickness, with various other thicknesses therebetween. The minimum thickness is less than an original thickness of a reference cradle in which the thickness is the same. The variable gauge cradle allows specific locations to be locally increased in thickness to achieve the desired stiffness at the areas requiring the increased stiffness, while leaving areas requiring a lower stiffness at a lesser thickness. The variable gauge cradle therefore may have a lower mass than the reference cradle. The thickness may be increased relative to the minimum thickness using patches that are bonded to a base layer or panel of the cradle. The patches may be distributed at different locations to create different thicknesses.

摘要： A system for modifying the range capability of an electric vehicle includes a vehicle body having a front axle and a rear module secured to the vehicle body. The rear module includes a rear axle and the rear module is detachable from the vehicle body and replaceable with another rear module. The rear modules may include different range extension capabilities. The rear modules may include a battery or a combustion engine that may supplement the standard battery and electric motor of the vehicle. A pair of laterally translatable pins of the rear module may be moveable into and out of engagement with the vehicle body. The rear module may also include vertically extending posts that engage with the vehicle body. The vehicle body may be raised to disengage the posts from the vehicle body.

摘要： A sliding door system for a vehicle includes a door frame defining a door opening and a sliding door covering at least a portion of the door opening in a closed position. An upper door slide assembly and a lower door slide assembly collectively interconnect the sliding door to the door frame and each are configured to slide the sliding door relative to the door frame from the closed position to an open position to dispose the sliding door either forward or rearward of the door opening. The lower door slide assembly includes a lower track extending along the sliding door and a lower hinge assembly pivotably connected to the door frame and slideably mated with the lower track for effectuating pivoting and sliding movement of the sliding door between the open and closed positions.

摘要： A rotor for a wound-field synchronous machine (WFSM) comprises a core having a base with a ring-shaped cross-section extending between an outside surface and an inside surface defining a bore. The rotor also comprises a plurality of field windings spaced apart from one another at regular angular intervals and each extending around the base of the core, adjacent the outside surface and through the bore. Rotor field windings having radial, or spoke configurations are provided. Rotor field windings having V-shaped arrangements, in which two field windings each contribute to the production of each pole, are also provided. Rotors having permanent magnets in addition to field windings are also provided.

摘要： A wave rolling assembly and a process for manufacturing a component for a vehicle using the wave rolling assembly is provided. The process includes conveying a metal coil through a first leveler to present a metal sheet, and conveying the metal sheet through a looping pit. The metal sheet travels from the looping pit to the wave rolling assembly for forming a plurality of waves along the side edges of the metal sheet. The wave rolling assembly stretches the metal sheet. The wave rolling assembly can include a die assembly or a roll forming apparatus. The metal sheet is then conveyed through a second leveler to flatten the metal sheet. The metal sheet is cut into blanks and formed into the finished component in a blanking press and die assembly. Less scrap is generated due to the reduced thickness along the edges and overall increased width of the blanks.

摘要： A door structure system for a vehicle includes an inner panel, an outer panel, and an outer belt reinforcement member. The outer belt reinforcement member extends in a fore-and-aft direction of the door structure. The outer belt reinforcement member creates an overlap joint with a hem flange portion of the inner panel. The outer belt reinforcement member includes touch-down feature that extends toward the inner panel and into contact with a bearing surface of the inner panel that is stepped down relative to the hem flange portion. The overlap joint and the touch-down feature both contribute to an increased upper frame stiffness of the door structure and improve sealing performance between the door structure and the vehicle body structure.

摘要： A smart trim die assembly for providing multiple internal operations during a stroke. The smart trim die assembly (10) comprises a first die (12), a second die (14), and a cavity (20) formed between the first die and second die. A plurality of sensors (22) are located between the first die and the second die for measuring the distance therebetween during a stroke. A series of tools are integrated into one of the first die or second die and each perform one of trimming, piercing, dimpling, and tapping operations. The smart trim die assembly further includes a processor (210) and a memory device (214) for receiving readings from the sensors. The memory device further contains instructions that, when executed by the processor, cause the processor to, in response to the sensor reading a predetermined distance, instruct the series of tools to perform one or more of the operations.
