Tribology and Dynamics of Engine and Powertrain: Fundamentals, Applications and Future Trends Cover

 

Synopses & Reviews

Publisher Comments:

Tribology, the science of friction, wear and lubrication, is one of the cornerstones of engineerings quest for efficiency and conservation of resources. Tribology and Dynamics of Engine and Powertrain: Fundamentals, Applications and Future Trends provides an authoritative and comprehensive overview of the disciplines of dynamics and tribology using a multi-physics and multi-scale approach to improve automotive engine and powertrain technology. 

Part one reviews the fundamental aspects of the physics of motion, particularly the multi-body approach to multi-physics, multi-scale problem solving in tribology. Fundamental issues in tribology are then described in detail,from surface phenomena in thin-film tribology, to impact dynamics, fluid film and elastohydrodynamic lubrication means of measurement and evaluation. These chapters provide an understanding of the theoretical foundation for Part II which includes many aspects of the physics of motion at a multitude of interaction scales from large displacement dynamics to noise and vibration tribology, all of which affect engines and powertrains. Many chapters are contributed by well-established practitioners disseminating their valuable knowledge and expertise on specific engine and powertrain sub-systems. These include overviews of engine and powertrain issues, engine bearings, piston systems, valve trains, transmission and many aspects of drivetrain systems. The final part of the book considers the emerging areas of microengines and gears as well as nano-scale surface engineering. 

With its distinguished editor and international team of academic and industry contributors, Tribology and Dynamics of Engine and Powertrain is a standard work for automotive engineers and all those researching NVH and tribological issues in engineering.

Book News Annotation:

"Tribology is now one of the cornerstones in the quest for efficiency, conservation of resources and the protection of ecosystems," states Rahnejat (dynamics, Wolfson School of Mechanical and Manufacturing Engineering, UK) in his preface. He goes on to explain that conservation of energy resources used for cars is crucial, and that fundamental to efficient cars is the science of friction, wear and lubrication. What is problematic is that the subject gets overwhelmingly complex at the molecular level, and yet power train designs that cut corners in their consideration of friction wind up with noise and vibration flaws that are expensive to fix. Continuing, the author points out that instructed by nature, engineers can pursue designs that adhere to "a quest for the principle of least action." The subject is addressed in terms of "multi-physics, multi-scale problem solving" in 33 chapters written by mostly UK engineers, with a handful from the US, Europe, and elsewhere. After introductory chapters on the fundamentals of dynamics within the multi-physics environment, coverage proceeds to surface phenomena in thin-film tribology, impact dynamics of semi-infinite and layered solids, and elastohydrodynamic lubrication. Following is detailed discussion of engine and powertrain technologies and applications in chapters on piston systems, valve train systems, and engine bearings, among other topics.

Synopsis:

Tribology is one element of many interacting within a vehicle engine and powertrain. In adopting a detailed, theoretical, component approach to solving tribological problems, the minutiae can be overwhelmingly complex and practical solutions become elusive and uneconomic. The system perspective generally adopted in industry, however, can lead to shortcuts and oversimplifications, industrial projects are subject to ad hoc trial and error, and subsequent ‘fire-fighting’ activity is required. This book seeks to bridge this divide, using a multi-physics approach to provide sufficient fundamental grounding and understanding of both detailed and approximate analysis – thereby making ‘first time right’ design solutions possible. Tribological issues and solutions in piston systems, valve train systems, engine bearings and drivetrain systems are addressed. New developments in materials, micro-engineering, nano-technology and MEMS are also included.
