The new Supplying PSA Peugeot Citroën analyses the ways in which PSA Peugeot Citroën is moving forward in terms of models and technology, including what issues are affecting the OEM in terms of supply and manufacturing. The report is based on interviews with key purchasing executives. Although PSA is being negatively affected by the economic situation in Europe, the carmaker is set to kick off an aggressive period of growth in China, still the largest and strongest new car market in the world. This is backed by joint-ventures with local partners Dongfeng and Chang An, both in terms of production and also in R&D. Advanced build and powertrain solutions will serve as the basis of a series of new vehicles, the development of which will be supported by the EUR3 billion of liquidity generated by direct company investment and new share offerings. How this plays out over the remainder of the decade and into the 2020s will be critical to the future of PSA. Should these strategies deliver success, then the OEM is virtually guaranteed a continued place at the top table of global car manufacturers.

Abstract The development of weldable high-strength and wear-resistant steels have made modern structures such as booms and mobile equipment possible. These sorts of novel and effective designs could not be constructed with traditional mild steel. Unfortunately, the use of these novel steels requires proper design, and there is no practical design code for these novel steels. This paper addresses stability issues, which are important considerations for designs with high-strength steels, and the properties of the heat-affected zone, which may require special attention. Fatigue design is also discussed in this paper, and the importance of the weld quality is highlighted, along with discussions on which details in the weld are the most important. By comparing the test results with the classical load limit solution, it is determined that full plastic capacity is reached and that the samples display good strain properties. Additionally, the reliability of the classical formulas is shown by comparing them to a recently proposed, novel formula.

This standard specifies a procedure for approximating the volume of materials contained in the grapple of bucket linkage operated grapples mounted to excavators. The volume ratings are based on the inside dimensions of the grapple and representative volumes extending beyond the grapple. The method employs the technique of dividing the complex shape of the material in the grapple into simple geometric forms to allow volume calculations of different grapple configurations. The rating method is intended to provide a consistent means of comparing grapple capacities. It is not intended to define actual capacities that might be observed in any specific application.

This SAE Standard covers the mechanical and material requirements for inch-series steel bolts, screws, studs, screws for sems , and U-bolts in sizes to 1-1/2 in. inclusive. The term “stud” as referred to herein applies to a cylindrical rod of moderate length threaded on either one or both ends or throughout its entire length. It does not apply to headed, collared, or similar products which are more closely characterized by requirements shown herein for bolts. The mechanical properties included in Table 1 were compiled at an ambient temperature of approximately 20 °C (68 °F). These properties are valid within a temperature range which depends upon the material grade used and thermal and mechanical processing. Other properties such as fatigue behavior, corrosion resistance, impact properties, etc., are beyond the scope of this document and responsibility for ensuring the acceptability of the product for applications where conditions warrant consideration of these other properties shall be borne by the end user.

This SAE Aerospace Information Report (AIR) describes the performance of platings and coatings for landing gear that potentially provide environmental compliance benefits versus the current baseline processes. The hazardous systems addressed in this version of the document include cadmium plating, chromated primers, and high VOC (volatile organic compounds) topcoats. Available data are presented for various standard tests in order to compare the replacement candidates. Conclusions are made as to the best performer(s) for each test section presented. These conclusions are not to be regarded as recommendations for or against any of the candidates. The AIR applies to landing gear structures and mechanisms for all types of civil and military aircraft. The potential replacements apply to both original equipment manufacturer (OEM) hardware and overhaul of in-service landing gears.

Abstract Environment, energy and safety concerns for vehicles have made improving strength-to-weight ratio of vehicles an imperative issue for the automobile industry. Tube hydroforming (THF) is an innovative forming technology, which can efficiently reduce the weight of a component or assembly, and at the same time, increase the part strength. THF produces parts with a high degree of part complexity (various cross-sections in a single piece) and dimensional stability. Tube hydroforming involves the expansion and sizing of tubes in a closed die under dynamic action of pressurized fluid, with simultaneous axial or radial compression. Best forming results can be achieved by the optimized combination of process parameters (internal pressure, feed, friction, load, blank thickness) and material properties (yield strength, tensile strength, n-value, r-value, elongation).With the help of case studies, this thesis presents how tube hydroforming has been used to shave mass off some conventionally produced auto components like chassis cross-members, trailing arms, crash members and exhaust housings.

Abstract Development of economical, as rolled, high strength low alloy steels is the requirement of the day due to its unique features such as increased strength, toughness, formability and weldability property. These materials are required for a variety of critical applications such as long and cross members of auto chassis, pre-engineered building (PEB) structures etc. In line with the developmental trend and market requirement, special quality hot rolled formable grades such as HSFQ 350/ 450 (High Strength Formable Quality) have been selected for development at Rourkela Steel Plant (RSP). The newly developed HSFQ hot rolled steel possess an attractive combination of strength and formability property which is typically quantified as high elongation (25 % min) and hole expansion ratio (145 % min) coupled with lower YS/UTS ratio (0.80-0.85). This has been possible as a result of innovative alloy design and synergistic effect of Nb & Si during controlled processing. Similarly medium carbon steels are being used for wide range of automotive applications.
