Increasing fuel economy standards have motivated automakers to reduce vehicle mass with multi-material bodies-in-white. One joining technology particularly suited for onesided multi-material joining is Flow Drill Screwdriving (FDS), a process by which a fastener friction drills, penetrates the joint, thread-forms, and then torques to apply clamping pressure to the joint. The frictional nature of FDS induces thermal softening of the material but requires time for the heat to build. Prior work with thermal assistance has shown that increasing pre-process temperature leads directly to reducing penetration time, but may add to overall cycle time. A more efficient augmentation approach through Electrical Augmentation (EA) is investigated to reduce cycle time. An experimental investigation of the EA-FDS process is presented, with the joint metrics quantified through installation torque, process time, and breakloose torque. EA-FDS is shown to reduce cycle time, and have the ability to join thicker cross-sections.

Light weight materials which possess high strength and durability are being utilized by the automotive industry to increase fuel economy. Rapidly solidified (RS) Al alloys are currently being extensively studied for this purpose. In this investigation the microstructure of an extruded Al-8Fe-2Mo alloy, produced by Pratt & Whitney Aircraft, Goverment Products Div. was examined in a JE0L 2000FX AEM. Both electropolished thin sections, and extraction replicas were examined to characterize this material. The consolidation procedure for producing this material included a 9:1 extrusion at 340°C followed by a 16:1 extrusion at 400°C, utilizing RS powders which have also been characterized utilizing electron microscopy.

ABSTRACT Maintaining proper tire inflation is the number one issue facing commercial fleets today. Common, slow-leaking tread area punctures along with leaking valve stems and osmosis through the tire casing lead to tire underinflation with a subsequent loss in fuel economy, reduction in retreadability, tread wear loss, irregular wear, and increase in tire-related roadside service calls. Commercial truck tires are the highest maintenance cost for fleets second only to fuel. This article will examine tire footprint analysis, rolling resistance data, and the effect on vehicle fuel economy from tires run at a variety of underinflated, overinflated, and recommended tire pressures. This analysis will also include the tire footprint impact by running tires on both fully loaded and unloaded trailers. The footprint analysis addresses both standard dual tires (295/75R22.5) along with the newer increasingly popular wide-base tire size 445/50R22.5.
