Light-duty pickup trucks have been and are an important growing segment of the US automotive market. Like all other vehicles on the road, they must also do their part to conserve fuel and weight reduction is a vital tool for achieving this goal. Tailgates currently installed on pickup trucks typically weigh over 30 lbs. and weight loss in these panels is very desirable. Recent demographic shifts in truck users has also lead to more interest in light-weighting of components like the tailgate for ergonomic reasons. Manufacturers have reached the limit for light-weighting tailgates using current materials and manufacturing processes. This new concept changes the paradigm. It uses a hybrid system of aluminum and plastic composite materials along with new manufacturing and assembly processes to achieve a significant weight reduction without compromising performance or other desired attributes. This paper describes the design and demonstrates its viability via analysis and test results.

Light weighting of vehicle doors is a challenge faced by all vehicle manufacturers - whether passenger cars and vans or large commercial vehicles like trucks and buses. This need is driven not only by the desire to improve the vehicle's fuel economy, but also by the implication of the doors on the buyer's perception of the vehicle's quality. The best solutions to these needs emerge from an unbiased consideration of different materials and product forms in the design and development of lightweight doors. To demonstrate this notion, a truck door was designed that has the potential of providing both improved fit as well as enhanced structural performance. The concept also simplifies the manufacturing process thereby minimizing system cost while offering approximately 7% additional weight saving compared the door already made from light weight materials (aluminum).

A light weight, cost effective IP reinforcement structure with a high degree of resistance to steering wheel vibration and with a safe and efficient crash energy management has been developed by Alcoa Automotive Structures (AAS). It also demonstrates other desirable attributes like modularity for world-car platform applications and improved dimensional consistency. The design was analyzed using finite element methods (FEM) for vibration and crash performance and prototype assemblies have been tested. Results demonstrate conformance to vibration and crash response expectations. The concept demonstrates viability and benefits of Alcoa's multiple material and product form solution for IP structures. This paper describes the design and shows some of the analysis and test results

For years, producers of low to medium volume products of high unit cost have been faced with the questions-“How much do we test?” and “What if we don't?” Today, manufacturers cannot compete in the market if these questions are not answered. This paper presents a methodology for answering these questions quantitatively. It applies Bayes Theorem of “apriori knowledge” to generate a probabalistic model of the new product testing task. It uses the existing knowledge and expertise within the organization and a simple matrix technique to determine the testing needs for the project at hand. This paper is intended to address the issues of durability and reliability of new products that are manufactured in relatively low volumes, such as Lift Trucks and Farm Equipment and/or products of high unit cost such as construction or off highway machinery.
