Engineers at NASA and Boeing are amongst the believers who foresee folding wings in-flight using advanced materials and technologies being a potential game-changer for future aircraft. The two organization have teamed to develop an actuation system that uses an SMA that will accomplish this goal using less complex, lighter, and more compact hardware than conventional systems.

Abstract The present work deals with the fabrication and tribological testing of an aluminium/SiC composite. Fabrication was done using two techniques; mechanical stir casting and electromagnetic stir casting. Metal matrix composite (MMC) was fabricated using aluminium as a matrix and SiC as reinforcement in varying weight percentages. The wear and frictional properties of the MMC were studied by performing dry sliding wear test using a pin-on-disc wear tester for both types of samples. Wear rate retards with the increase the percentage of reinforcement whereas it improves with the addition of normal force. At same time frictional coefficient upsurges by increasing the normal force and percentage of reinforcement. Increasing percentage of reinforcement and using electromagnetic stir casting process obtained the higher frictional coefficient and lower wear rate.

General criteria are presented as guidelines for: control device location, resistance, and actuation of hand and foot controls by the machine's operator. The criteria are based upon physical limitations as defined by human factors engineering principles. This SAE Recommended Practice applies to upright seated operators of Road Building and Maintenance, and Specialized Mining Machinery categories of off-road, self-propelled work machines as identified in SAE J1116. The criteria presented should apply to most situations. Each situation, however, must be evaluated as to its own function and its relationship to other functions to achieve the desired operation action in normal and emergency situations with high probability. The values for control displacement and resistance apply only to what is required to achieve the desired performance of the function being controlled for the 5th through the 95th percentile person as defined in ISO 3411.

J2613_201710
This SAE Standard covers sub-critically annealed or normalized electric resistance welded flash controlled single-wall high strength steel tubing intended for use in hydraulic pressure lines and in other applications requiring tubing of a quality suitable for bending, double flaring, cold forming, welding and brazing. Material produced to this specification is not intended to be used for single flare applications due to the potential leak path caused by the ID weld bead. Nominal reference working pressures for this tubing are listed in ISO 10763 for metric tubing and SAE J1065 for inch tubing. This specification also covers SAE J2613 Type-A tubing. The mechanical properties and performance requirements of standard SAE J2613 and SAE J2613 Type-A are the same. The designated differences of Type-A tubing do not imply that Type-A tubing is in anyway inferior to standard SAE J2613.

This SAE Recommended Practice pertains to blast cleaning and shot peening and provides for standard cast shot and grit size numbers. For shot, this number corresponds with the opening of the nominal test sieve, in ten thousandths of inches1, preceded by an S. For grit, this number corresponds with the sieve designation of the nominal test sieve with the prefix G added. These sieves are in accordance with ASTM E 11. The accompanying shot and grit classifications and size designations were formulated by representatives of shot and grit suppliers, equipment manufacturers, and automotive users.

Abstract Bio-butanol has been widely investigated as a promising alternative fuel. However, the main issues preventing the industrial-scale production of butanol is its relatively low production efficiency and high cost of production. Acetone-butanol-ethanol (ABE), the intermediate product in the ABE fermentation process for producing bio-butanol, has attracted a lot of interest as an alternative fuel because it not only preserves the advantages of oxygenated fuels, but also lowers the cost of fuel recovery for individual component during fermentation. If ABE could be directly used for clean combustion, the separation costs would be eliminated which save an enormous amount of time and money in the production chain of bio-butanol.

Abstract Different mechanical components in a vehicle can be made from different steel alloys with various surface treatments or coatings. Lubricant technology is needed to prevent wear and control friction on all of these different surfaces. Phosphorus compounds are the key additives that are used to control wear and they do this by forming tribofilms on surfaces. It has been shown that different operating conditions (pressures and sliding conditions) can influence the formation of tribofilms formed by different anti-wear additives. The effect of surface metallurgy and morphology on tribofilm formation is described in this paper. Our results show that additive technology can form proper tribofilms on various surfaces and the right combination of additives can be found for current and future surfaces.

Abstract The vehicle driveline suffers low frequency torsional vibration due to the abrupt change of input torque and torque fluctuation under variable frequency. This problem can be solved by model based control, so building a control oriented driveline model is extremely important. In this paper, an on-line recursive identification method is proposed for control oriented model and validated based on an electric car. First of all, the control oriented driveline model is simplified into a six-parameter model with double inertia. Secondly, based on stability analysis, motor torque and motor speed are chosen as input signal for on-line model identification. A recursive identification algorithm is designed and implemented based on Simulink. Meanwhile a detail model of the vehicle which considering driveline parameter variation is built based on ADAMS. Thirdly, on-line identification is conducted by using co-simulation of ADAMS and Simulink.
