Die Lebensdauer von Verzahnungen wird durch Zahnbruch (Zahnfusstragfahigkeit), Grubchenbildung (Zahnflankentragfahigkeit) oder Verschleiss (Fresstragfahigkeit) be- grenzt. Die jeweiligen Festigkeiten sind dabei bestimmt durch die Beanspruchung, die Geometrie der Verzahnung sowie durch die gewahlten Werkstoffe. In DIN 3990 [7/11 werden zur Berechnung der Tragfahigkeit funf Verfahren (A, B, C, D, E) darge- stellt. Die folgenden Ausfuhrungen beschranken sich ausschliesslich auf Verfahren B, das fur die numerische Berechnung besonders geeignet ist. Grundlage der Tragfahigkeitsberechnung von Gerad- und Schragstirnradern bilden Berechnungsmethoden nach DIN 3990 [7/1] . Nach dieser Norm umfasst die vollstan- dige Tragfahigkeitsberechnung einer Zahnradpaarung die UEberprufung der Zahn- fuss-, Zahnflanken- und Fresstragfahigkeit. Als Belastung des Zahnradpaares wird dabei die statische Nenn-Umfangskraft Ft (am Teilkreis im Stirnschnitt) angesetzt, die direkt aus der vom Zahnpaar ubertragenen Leistung berechnet werden kann. 1) 2M an F - 2P (7.1) t(t) - dt1-w1 = dt1 Um die von innen und aussen auf ein Getriebe wirkenden dynamischen Zusatzkrafte sowie die durch Toleranzen und Verformungen hervorgerufene ungleichmassige Lastver- teilung zu berucksichtigen, werden allgemeine Einflussfaktoren bestimmt. Die mit die- sen Einflussfaktoren und der statischen Umfangskraft Ft ermittelte Belastung geht in der Berechnung der Tragfahigkeit als massgebliche Belastung ein.

Kanalnetzuberlastungen, Grundwasserabsenkungen und Hochwasserspitzen sind nur einige negative Auswirkungen der Versiegelung auf den naturlichen Wasserhaushalt. Gerade die neueren Entwicklungen hinsichtlich der Neufassung von Bodenschutzgesetzgebung, Landeswassergesetzen und kommunalen Abwassersatzungen zur Foerderung des schonenden Umgangs mit Boden und Wasser lassen die Bedeutung von oekologischen Bauweisen immer wichtiger erscheinen. Der Einsatz versickerungsfahiger Verkehrsflachenbefestigungen ist hierbei ein zunehmend unentbehrlicher Baustein, um Regenwasser wieder naturnah zu bewirtschaften und damit die weitreichenden Folgen der Versiegelung zu verringern. Beim Einsatz versickerungsfahiger Befestigungssysteme sollen aufgrund ihrer Konstruktion Niederschlage direkt auf der Flache aufgenommen und somit durch verringerte Oberflachenabflusse die Kanalisation entlastet und die Versiegelung vermindert werden.
Most approaches that contribute to the design of life-critical systems almost only consider nominal situations where procedures can be developed and used to achieve satisfactory operations. These kinds of approaches lead to rigid ways of doing things and poorly address the needs for flexibility, especially when things go wrong. It is not a matter of human adaptation but of human systems integration (HSI) flexibility. HSI flexibility requires cross-fertilization of appropriate experiences combined with creativity. This book provides risk-management approaches and methods for combining prevention and design. Features: Discusses risk-management approaches and methods for combining prevention and design Examines a transdisciplinary approach to risk management in design and operations of safer life-critical systems Proposes an approach of work analysis during design, which enables design teams to consider HSI issues early enough to fix organizational problems upstream Teaches the combination of prevention and design for safety management This book gathers and analyzes relevant field data to rationalize human and systems activity in various life-critical environments and workplaces, in a systemic manner, and in a variety of safety domains (e.g., aviation, road, navy, manufacturing, hospital, transportation, defense, sport). It further formalizes and analyzes risk-taking experience, expertise, stories about critical events, and scientific and professional literature data to help engineering designers, managers, and health and safety specialists. The text is primarily written for graduate students and professionals working in the fields of occupational health and safety, ergonomics, human factors, cognitive engineering, and human-system integration.
Electric drive vehicles (EDVs) are seen on American roads in increasing numbers. Related to this market trend and critical for it to increase are improvements in battery technology. Battery Technology for Electric Vehicles examines in detail at the research support from the U.S. Department of Energy (DOE) for the development of nickel-metal-hydride (NiMH) and lithium-ion (Li-ion) batteries used in EDVs. With public support comes accountability of the social outcomes associated with public investments. The book overviews DOE investments in advanced battery technology, documents the adoption of these batteries in EDVs on the road, and calculates the economic benefits associated with these improved technologies. It provides a detailed global evaluation of the net social benefits associated with DOEs investments, the results of the benefit-to-cost ratio of over 3.6-to-1, and the life-cycle approach that allows adopted EDVs to remain on the road over their expected future life, thus generating economic and environmental health benefits into the future.
This book focuses on the use of AI/ML-based techniques to solve issues related to IoT-based environments, as well as their applications.

Alternative Fuel Vehicles gives full coverage of all associated qualifications and awards in the emerging field of alternative fuels. It is an essential introduction to the ever-growing demand for vehicles that operate using non-conventional fuels. This first book on AFVs endorsed by the IMI begins with an overview of the subject, ideal for beginners, before outlining what is meant by alternative fuels, why they are necessary, and why climate change and associated legislation are key drivers. Details of how alternative fuels are made, the supply infrastructure, and how these vehicles work are all included. A chapter on fuel cells introduces learners to the use of hydrogen, and one on engines and engine management includes coverage of combustion as an aid to understanding why changing the type of engine fuel is complex. Some basic engine technology is included to help readers new to the subject. Real-life case studies and examples are used to illustrate different technologies in current use, and to speculate on new developments. This book is an ideal companion to any unit of study on alternative fuel, but will also be of interest to working technicians and keen amateurs.

Design or build a battery-powered electric bicycle For much of the world, bicycles are a transportation mainstay. Electric bicycles----powered by a rechargeable battery pack----are proven to deliver the highest possible energy efficiency, even compared to pedal bikes. A transportation alternative to fossil fuels, electric bicycles are fast catching on, in part because they don't require factory assembly. End-users can easily construct them with available components. The text reveals important techniques, data, and examples that allow readers to judge various propulsion setups----used in both home- and factory-made bikes----and estimate speed and travel distance for each. Numerous charts clearly present the costs, benefits, and trade-offs between both commercial and user-converted models. Key features include: Estimating motor-performance for wind, hill, and cruising power requirements Estimating battery capacity and a thorough description of battery charging Motor and motor-control options Evaluating motor-to-wheel coupling options Placement of propulsion components Configurations and performance How systems-engineering techniques can produce electric-bicycle designs that have long travel range and low life-cycle cost Testing Developments to watch A comprehensive resource for harnessing innovation, Electric Bicycles is the definitive practical guide to taking full advantage of this exciting alternative energy technology.
Mit der Renaissance des Schienenverkehrs hat das Spezialgebiet "Schienenfahrzeugdynamik" an Bedeutung gewonnen. Auf entsprechendes Interesse wird das erste Buch im deutschsprachigen Raum stossen, das hier seinen Schwerpunkt hat. Obwohl es auf der Vorlesung "Schienenfahrzeugdynamik" an der TU Berlin basiert und Vorkenntnisse bezuglich Mechanik, Schwingungslehre und angewandter Mathematik voraussetzt, spricht es auch den Praktiker an. Das Buch behandelt die Vertikaldynamik bis hin zu Komfortbetrachtungen und die Lateraldynamik so weit, dass dem Leser ein Verstandnis der Stabilitat von Schienenfahrzeugen moglich ist. Den Vorgangen im Kontakt Rad/Schiene wird besondere Aufmerksamkeit gewidmet. Es enthalt die jungsten Erkenntnisse aus Forschung und Bahnpraxis. Die Autoren gehen detailliert auf die spezielle Terminologie der Schienenfahrzeugdynamik und benachbarter Fachgebiete ein."
