Autonomous Vehicle Engineering: March 2018

Editorial Autonomy's data binge is more like a 5-course meal. Big Data, Big Challenges Cloud services and multiple partnerships are issues the mobility industry grapples with as data implications expand outside the vehicle. Reinventing the Automobile's Design The convergence of electric propulsion, Level 5 autonomy, and the advent of car-free urban zones, is driving new approaches to vehicle design and engineering. When Steering Isn't Steering Anymore High-level autonomy requires new thinking for even basic vehicle controls. Steer-by-wire technology eases some of the complexities automated driving presents-and offers desirable new possibilities. Autonomy and Electrification: A Perfect Match? Combining SAE Level 4/5 functionality and EV platforms brings chal-lenges-and opportunities for cost reduction and systems optimization. Who's Ahead in the Automated-Driving Race? The 2018 Navigant Research Leaderboard study brings interesting insights on the industry's progress.

The Tao of Measurement

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.

Voiture Minimum

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.

Introduction to Dynamics of Rotor-Bearing Systems

This book is written as an introduction to rotor-bearing dynamics for practicing engineers and students who are involved in rotor dynamics and bearing designs. The goal is to provide a step-by-step approach to the understanding of fundamentals of rotor-bearing dynamics. Therefore, the emphasis is on the basic principles, phenomena, modeling, theory, and interpretations of the results. Introduction to Dynamics of Rotor-bearing Systems includes numerous examples, from a single-degree-of-freedom system to complicated industrial rotating machinery, which serve to illustrate fundamental dynamic behaviors. The concepts in the text are reinforced by parametric studies and numerous illustrative examples and figures.

Birdflight as The Basis of Aviation

Scientists and aviation enthusiasts from around the world will find this one of the most important books ever published. It's the work of the German aviation pioneer and creative genius, Otto Lilienthal, whose observation, analysis, ingenuity and daring laid the foundation for the development of aviation. The "Flying Man" Lilienthal was the first man to launch himself into the air, fly, and land safely. First published in 1891, this new edition is an unabridged copy of the original complete with Lilienthal's own diagrams and formulae, and a preface written in 1911 by A.W. Isenthal, who translated the original into English after Lilienthal's death. After a comprehensive scientific study of how birds fly, Lilienthal recognized the superiority of curved wing surfaces. He then developed a theory of flight and designed and built a series of gliders. From 1891 to 1896 he made over 2,000 glides-bridging the gap between those who dreamed of flying and those who flew.

The Modeling of Mold Filling in Structural Reaction Injection Molding

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.
