Noise and Torsional Vibration Analysis of Hybrid Vehicles by Xiaolin Tang,Yanjun Huang,Hong Wang,Yechen Qin Pdf

Thanks to the potential of reducing fuel consumption and emissions, hybrid electric vehicles (HEVs) have been attracting more and more attention from car manufacturers and researchers. Due to involving two energy sources, i.e., engine and battery, the powertrain in HEVs is a complicated electromechanical coupling system that generates noise and vibration different from that of a traditional vehicle. Accordingly, it is very important to explore the noise and vibration characteristics of HEVs. In this book, a hybrid vehicle with two motors is taken as an example, consisting of a compound planetary gear set (CPGS) as the power-split device, to analyze the noise and vibration characteristics. It is specifically intended for graduates and anyone with an interest in the electrification of full hybrid vehicles. The book begins with the research background and significance of the HEV. The second chapter presents the structural description and working principal of the target hybrid vehicle. Chapter 3 highlights the noise, vibration, and harshness (NVH) tests and corresponding analysis of the hybrid powertrain. Chapter 4 provides transmission system parameters and meshing stiffness calculation. Chapter 5 discusses the mathematical modeling and analyzes torsional vibration (TV) of HEVs. Finally, modeling of the hybrid powertrain with ADAMS is given in Chapter 6.

The Radio Noise Spectrum by Donald Howard Menzel Pdf

This modern era has had many names: the golden age, the machine age, the atomic age, the electronic age, and so on. One further title, hitherto unpublicized, it eminently deserves: the age of noise. Man has compounded the natural noise that preceded his existence on the earth until no point on this globe is free from it. Even in the desert's hush, radio waves pervade the air and provide a source of potential noise. The shorter waves escape from the earth and fill interplanetary space with the mingled clamor of FM, TV, radar, and other insistent voices. This book deals with the important problem of radio noise, its sources, whether manmade or natural, over the known range of frequencies. Certain of these contributions will interest the communicator, enabling him to estimate the potential interference from various types of sources. Other contributions deal mainly with scientific problems, such as the origins and significance of certain characteristic noise radiations. The contributors to this book are experts on the various phases of radio noise. The individual chapters derive from papers presented at a Conference on Radio Noise, held at Harvard College Observatory, April 22, 1958.

Planetary Noise by Erín Moure Pdf

Planetary Noise: Selected Poetry of Erín Moure gathers four decades of poetry from a celebrated Canadian poet and translator who has persistently reconfigured the linguistic and material relations of English. Moure’s poems and networked sequences are hybrid and often polylingual; they work with contradiction, paradox, and verbal detritus— linguistic hics and blips often too quickly dismissed as noise—to create new conditions for thought and pleasure. From postdramatic theatre to queer and feminist theory, from the politics of citizenship and genocide to the minutiae of digital poetics, from the clamor of love to the shadows of grief and memory, Moure has joyously toppled hierarchies of meaning and parasited dominant discourses to create poetry that crosses borders, embracing hope, not war. This volume, edited by poet and literary scholar Shannon Maguire, also features an extensive introduction to Moure’s poetry, a section of poetry by others translated by Moure, and an afterword on translation by the poet. An online reader’s companion is available at wesleyan.edu/wespress/readerscompanions.

Noise Matters by Greg Hainge Pdf

Everyone knows what noise is. Or do they? Can we in fact say that one man's noise is another teenager's music? Is noise in fact only an auditory phenomenon or does it extend far beyond this realm? If our common definitions of noise are necessarily subjective and noise is not just unpleasant sound, then it merits a closer look (or listen). Greg Hainge sets out to define noise in this way, to find within it a series of operations common across its multiple manifestations that allow us to apprehend it as something other than a highly subjective term that tells us very little. Examining a wide range of texts, including Sartre's novel Nausea and David Lynch's iconic films Eraserhead and Inland Empire, Hainge investigates some of the Twentieth Century's most infamous noisemongers to suggest that they're not that noisy after all; and it finds true noise in some surprising places. The result is a thrilling and illuminating study of sound and culture.

VIBRATION AND NOISE REDUCTION IN PLANETARY GEAR TRAIN BY PHASING by Ashutosh Mokate Pdf

Gears are essential parts of many precision power transmitting machines such as automobiles. The major functions of a gearbox are to transform speed and torque in a given ratio and to change the axis of rotation. Planetary gears yield several advantages over conventional parallel shaft gear systems: They produce high speed reductions in compact spaces, a greater load sharing, a higher torque to weight ratio, diminished bearing loads, and reduced noise and vibration. They are used in automobiles, helicopters, aircraft engines, heavy machinery, and a variety of other applications. Despite their advantages, the noise induced by the vibration of planetary gear systems remains a key concern. Planetary gears have received considerably less research attention than single mesh gear pairs. There is a particular scarcity of analysis of two planetary gear systems and their dynamic response. Hence, this book focuses on the study of two PGTs with different phasing (angular positions) while every individual set remains unchanged.

International Gear Conference 2014: 26th-28th August 2014, Lyon by Philippe Velex Pdf

This book presents papers from the International Gear Conference 2014, held in Lyon, 26th-28th August 2014. Mechanical transmission components such as gears, rolling element bearings, CVTs, belts and chains are present in every industrial sector and over recent years, increasing competitive pressure and environmental concerns have provided an impetus for cleaner, more efficient and quieter units. Moreover, the emergence of relatively new applications such as wind turbines, hybrid transmissions and jet engines has led to even more severe constraints. The main objective of this conference is to provide a forum for the most recent advances, addressing the challenges in modern mechanical transmissions. The conference proceedings address all aspects of gear and power transmission technology and range of applications (aerospace, automotive, wind turbine, and others) including topical issues such as power losses and efficiency, gear vibrations and noise, lubrication, contact failures, tribo-dynamics and nano transmissions. A truly international contribution with more than 120 papers from all over the world A judicious balance between fundamental research and industrial concerns Participation of the most respected international experts in the field of gearing A wide range of applications in terms of size, power, speed, and industrial sector

Noise by Hal Clement Pdf

Hal Clement, the dean of hard science fiction, has written a new planetary adventure in the tradition of his classic Mission of Gravity. It is the kind of story that made his reputation as a meticulous designer of otherworldly settings that are utterly convincing because they are constructed from the ground up using established principles of orbital mechanics, geology, chemistry, biology, and other sciences. Kainui is one of a pair of double planets circling a pair of binary stars. Mike Hoani has come there to study the language of the colonists, to analyze its evolution in the years since settlement. But Kainui is an ocean planet. Although settled by Polynesians, it is anything but a tropical paradise. The ocean is 1,700 miles deep, with no solid ground anywhere. The population is scattered in cities on floating artificial islands with no fixed locations. The atmosphere isn't breathable, and lightning, waterspouts, and tsunamis are constant. Out on the great planetary ocean, self-sufficiency is crucial, and far from any floating city, on a small working-family ship, anything can happen. There are, for instance, pirates. Mike's academic research turns into an exotic nautical adventure unlike anything he could have imagined.
