This book deals with the past, present, and future of flow, sensors, and measurement. It is called The Tao of Measurement because, like the Tao itself, it reveals the underlying principles of flow and measurement. It explains the engineering and physics of flow and sensors, how our units of measurement were derived, present day measurement practices, and how today's scientific tools can improve our units of measurement. The book's opening chapters explore the technologies of temperature, pressure, and flow measurement. The authors reveal the history of units of measurement and describe how they came to be used today. The book then presents a thorough discussion of the different types of temperature sensors, pressure transmitters, and flowmeters. It contains an explanation of applications, and then comments on trends in sensors and measurement. Each chapter includes a handy glossary of units of measurement.
HPD: HPM II Design Tool SAE Part#EA-3HPD The H-Point design tool is a set of data used during design in conjunction with the H-Point machine. In an IGES file format the HPM II is positioned in 1 neutral position and the 4 pre-defined postures. The file is uploaded into the resident CAD system and the user must add constraints and parametrics. The HPD is referenced in J 826_2002 as a critical component to the design applications of the HPM II.
Voted one of the top ten new design books, this lavishly illustrated book is a colorful account of Le Corbusier's love affair with the automobile, his vision of the ideal vehicle, and his tireless promotion of a design that industry never embraced. Le Corbusier, who famously called a house "a machine for living," was fascinated-even obsessed-by another kind of machine, the automobile. His writings were strewn with references to autos: "If houses were built industrially, mass-produced like chassis, an aesthetic would be formed with surprising precision," he wrote in Toward an Architecture (1923). In his "white phase" of the twenties and thirties, he insisted that his buildings be photographed with a modern automobile in the foreground. Le Corbusier moved beyond the theoretical in 1936, entering (with his cousin Pierre Jeanneret) an automobile design competition, submitting plans for "a minimalist vehicle for maximum functionality," the Voiture Minimum.

The main use of FRC in automobiles, with the exception of a few specialized low volume vehicles, has been until now in semistructural parts. One of the most promising process in development today, that may play major role in future structural composite fabrication, is based on SRIM technology. The rapid and extensive introduction of this process goes also through the development of deeper theoretical knowledge of the process and the development of computer simulation to aid mold design and choice of proper processing parameters. To contribute SRIM advancement, a preliminary model has been developed for viscosity changes, extent of the reaction and temperature rises, associated with the mold filling stage, as well as a simple software to evaluate the pressure drop through different combinations of reinforcements.
In order to improve the design of drawn parts and to reduce the number of trial and error tests, Renault has undertaken the development and the validation of various finite element procedures and codes. This paper describes the function of each software and its level of integration into the design process. One of them is already an operational tool used be planners whilst the others are still in the validation phase. Selected examples show typical applications of the computer programs on automotive parts.
In this paper the socio-economic and technical problems of the handling of car wrecks are discussed. The recovery of metals as a goal for shredder operations will increasingly be supplemented with the recovery of other materials such as polymers. In order to deal economically and technically with polymer materials, it is necessary to know in advance which type of wreck handling will be used. Also optimization of shredder operations allow less freedom to incorporate a variety of materials when compared with selective dismantling or disassemble of cars. It is argued that various technical solutions have to be accompanied by increased cooperation along the firms that are connected to the handling of car wrecks. Cooperation between the scrap context and designers is essential, in order to optimize dismantling practices according to criteria of environmentally preferred solutions.
Compression molding of thermoplastic sheets, consolidated or non- consolidated, reinforced with glass fibers (GMT, GRT) is applied as an economic production process in the automotive industry. The aim of this work is to evaluate how the physical and mechanical strength characteristics depend on the presence or absence of ribs and how component performance may be changed by modifying the molding parameters, altering the content and orientation of the reinforcement fibers in the ribbed areas. For this purpose, two statistical designs will be considered, the first carried out on a box type component without ribs, the second on the same component with a set of internal ribs. Two different materials with a PP matrix will be tested, a GMT reinforced with continuous random glass fibers and a 12 mm random glass fibers composite.
The purely theoretical evaluation of critical compression loads seems complex and not very reliable in the case of honeycomb panels, on account of the numerous parameters in play and their complex interrelationships. This report provides the designer with a fast tool for preliminary calculations, consisting of a finite-element mathematical model with elastic-linear code (which can be processed using a PC), which makes it possible to obtain information very closely resembling the real situation.
The pending changes in European law enabling the use of plastic lenses on vehicle headlamps provide an opportunity for further advancement of vehicle styling, lighting performance and aerodynamic efficiency.

The replacement with plastic of an important component, formerly in steel, in the timing drive of a heavily duty diesel engine has been studied and realized. The substituted part is the toothed coupling connecting the injection pump to the timing drive. Torque that stresses the coupling has been measured with laboratory tests. The tooth stresses have been calculated with FEM analysis. Finally, fatigue tests have been carried out directly on the engine at different loadings. The test results are consistent with the predicted behavior of this component.
A data bank developed to give a concrete help to the designer concerned with fatigue-prone structures made of composite materials is described. The data bank not only collects the available results of fatigue tests on these materials, but also makes easy their statistical analysis and comparison for design purposes. It is then believed to constitute also an useful research instrument for the development of design rules for well defined classes of composite materials.
