Lean Manufacturing for the Automotive Industry and Beyond Using Optical Metrology

Optical Metrology applications provide for advanced industrial measurements and real-time test monitoring. ARAMIS, DIC (Digital Image Correlation), and PONTOS (photogrammetry) are critical tools for non-contact, full-field measurement of 3D deformation and the true strain tensors. This technology is highly effective for model validation, allowing load frame data to be directly used by CAE engineers for advanced material properties and full-field structural response.

Resilient and Corrosion-Proof Rolling Element Bearings Made from Superelastic Ni-Ti Alloys for Mechanical Applications

Mechanical components (bearings, gears, mechanisms) typically utilize hardened construction materials to minimize wear and attain long life. In such components, loaded contact points (e.g., meshing gear teeth, bearing balls-raceway contacts) experience high contact stresses. The combination of high hardness and high elastic modulus often leads to damaging contact stress and denting, particularly during transient overload events such as shock impacts that occur during the launching of space vehicles or the landing of aircraft.

Advanced Thermal Management Solutions: Pumped Two Phase Cooling

To efficiently cool high-power electronics, lasers and other devices, advanced thermal management solutions are being developed including the use of pumped two-phase cooling. Traditional air and pumped single-phase cooling systems are large and heavy and in many cases, they cannot dissipate the necessary heat loads while maintaining the device below its maximum operating temperature. While Pumped Two Phase Cooling solutions offer a potentially lighter and more compact solution, they have not been broadly adopted by industry due to their increased complexity. Recent technical advancements have addressed many of these issues and the technology is poised for broader adoptions across many industries. Pumped two-phase cooling systems can now be tailored to meet increasing cooling requirements for a broad range of applications including high power electronics, laser diodes, and IGBTs. This presentation will provide design engineers with a better understanding of the fundamentals of pumped two-phase cooling technologies, including challenges, new solutions and opportunities for implementation.

Bob Reisse, ALHAT Project Manager, Langley Research Center, Hampton, VA.

Bob Reisse coordinates the design and testing of ALHAT (Autonomous Landing Hazard Avoidance Technology) sensors. In December, ALHAT instruments were melded to HUEY helicopters, which used sensors and an integrated computer system to provide guidance and assist pilots. The technology will also enable landing near specific resources and locations across the solar system, including the moon, Mars, and other asteroids.
