Advanced High Strength Steels (AHSS) are now commonly used in automotive body structural applications. The high strength of this grade classification is attractive to help reduce mass in the automotive body through reduction in thickness. Strength also supports improvements in safety requirements so that mass increases are minimized. In some specific grades of AHSS, energy absorption is possible in addition to the high strength. This course will review the definition and properties of AHSS and cover several common applications in automotive body structures.

Abstract: The vehicle driveline suffers low frequency torsional vibration because of the abrupt change of torque and torque fluctuation of variable frequency. This problem can be solved by model-based predictive control, so building a control oriented driveline model is extremely important. The traditional off-line identified model which does not consider driveline parameter variation such as damping of tire and suspension during vehicle operation cannot accurately reflect the true characteristics of the driveline vibrations. And usually the fixed stiffness is considered, this will cause modeling errors and worse result of vibration control, in this paper, an on-line recursive identification method is proposed and verified based on an electric car. First of all, as for the low frequency vibration, the control oriented model is simplified into a six-parameter model with double inertia.

Different mechanical components in a vehicle can be made from different types of steel and can even contain different steel alloys 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 loads) 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.

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.

The evolution and execution of automotive manufacturing are explored in this fundamental manual. It is an excellent reference for entry level manufacturing engineers and also serves as a training guide for nonmanufacturing professionals. The book covers the major areas of vehicle assembly manufacturing and addresses common approaches and procedures of the development process. Having held positions as both a University Professor and as a Lead Engineering Specialist in industry, the author draws on his experience in both theory and application to fill the gap between academic research and industrial practices. This concisely written, comprehensive review discusses the sophisticated principles and concepts of automotive manufacturing from development to applications and includes: • 250 illustrations and 90 tables. • End-of-chapter review questions. • Research topics for in-depth case studies, literature reviews, and/or course projects. • Analytical problems for additional practice.

The rapidly evolving demand for cost reductions and shrinking budgets makes the application and use of automated processes within the aerospace and space industries a necessity. While some view aerospace automation as the solution to reducing costs, others view automation technologies and processes as something that should be avoided when possible. Misunderstandings and assumptions about these complex systems can result in the improper selection and application of these systems, often leading to undesirable interactions with other elements of the assembly process and potentially, project failure.

The challenges associated with using composites as a replacement for aluminum reside primarily in the complex manufacturing processes and technologies for fabricating composite parts. The high cost of composites material and its manufacturing complexity have been inhibitors to the wide transfer of this technology to the non-aerospace market. The search for solutions to high manufacturing costs and efficient manufacturing processes have resulted in intense research by government, aerospace industry companies, and space agencies worldwide.
