Book excerpt: It is our pleasure to present these proceedings for “The Aerodynamics of Heavy Vehicles II: Trucks, Buses and Trains” International Conference held in Lake - hoe, California, August 26-31, 2007 by Engineering Conferences International (ECI). Brought together were the world’s leading scientists and engineers from industry, universities, and research laboratories, including truck and high-speed train manufacturers and operators. All were gathered to discuss computer simu- tion and experimental techniques to be applied for the design of the more efficient trucks, buses and high-speed trains required in future years. This was the second conference in the series. The focus of the first conference in 2002 was the interplay between computations and experiment in minimizing ae- dynamic drag. The present proceedings, from the 2007 conference, address the development and application of advanced aerodynamic simulation and experim- tal methods for state-of-the-art analysis and design, as well as the development of new ideas and trends holding promise for the coming 10-year time span. Also - cluded, are studies of heavy vehicle aerodynamic tractor and trailer add-on - vices, studies of schemes to delay undesirable flow separation, and studies of - derhood thermal management.

Download or read book The International Vehicle Aerodynamics Conference written by IMechE and published by Woodhead Publishing. This book was released on 2014-11-12 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerodynamics has never been more central to the development of cars, commercial vehicles, motorbikes, trains and human powered vehicles, driven by the need for efficiency: reducing carbon dioxide emissions, reducing fuel consumption, increasing range and alleviating problems associated with traffic congestion. Reducing vehicle weight makes it more challenging to ensure that they are stable and handle well over a wide range of environmental conditions. Lighter structures are also more vulnerable to aerodynamically induced vibration. Alongside this, customers demand an environment that is quiet, comfortable and maintains their vision of the world around them in all weathers. These aims must be met by designing vehicles that engage customers emotionally, promoting the brand values of manufacturers and operators. This can only be done by collaboration between designers and aerodynamicists. - Examine the latest developments in vehicle aerodynamic development - Explore opportunities to network and share experiences around different areas - Focus on future challenges and the engineering knowledge and technology required to resolve them - Discuss other areas of development including handling and stability, tyre aerodynamics and modelling, aeroacoustics and fluid structure interaction

The book presents a unique neuro-tyre model for both on-road and off-road situations, capable of computing the steering, braking characteristics, and soil compaction. Road vehicle characteristics are described, including the stability and control, roll centre and roll axis, and rollover mechanics. The road vehicle braking performance is also described, including the brake components, choice of brake, and the transient load transfer. Finally, the dynamics and control of multi-wheel combat vehicles are presented and described extensively. The book is dedicated to undergraduate and graduate engineering students, in addition to researchers, and the automotive industry. As well as provide the readers with a better understanding of vehicle dynamics and soil mechanics. The book is also beneficial for automotive industries looking for a quick and reliable model to be implemented in their main software.

Book Synopsis A Qualitative Experimental Study of Drag Reduction Devices for Tractor Trailers with Ground Effects by : Nicolas Robert Reed
Download or read book A Qualitative Experimental Study of Drag Reduction Devices for Tractor Trailers with Ground Effects written by Nicolas Robert Reed and published by . This book was released on 2014 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an experimental qualitative study of how drag reduction devices affect air flow around a tractor trailer. A 1/32 scale detail model of a truck with its trailer was used for testing in a 20"x14" low speed wind tunnel at the University of Tennessee Space Institute. Major modifications were made to the wind tunnel so that it would include a moving bed (floor) section for ground effect simulation. This was done to accurately simulate relative ground movement with the truck being held stationary in the tunnel flow. Drag reduction devices were designed based on aerodynamic fundamental understanding for streamlining the various zones of the truck readily available for flow path modifications or flow management around the truck. The drag reduction devices were fabricated using a desktop 3D printer. Flow visualization was performed using sewing (twisted) string as tufts to validate if there were any flow improvement effectiveness as a result the flow management devices. A total of 102 tests were performed. This was done using 24 unique drag reduction devices, which were tested in 28 different configurations. Wind tunnel speed was in the range of 55 to 70 PMH at a corresponding tunnel unit Reynolds number of 5.6*10^5 to 7.12*10^5. Observations show that each device affects the flow, locally, and that an overall change in aerodynamic efficiency (drag reduction) can be achieved by the addition of a number of these devices. Test results from this investigation showed that the addition of drag reduction devices did change flow paths under the tractor trailer and did provide methods for managing flow under the trailer. A possible novel method for addressing the wake zone behind the tractor trailer, by addition of drag reduction devices installed under the trailer, was also investigated. Quantitative measurements are needed to determine the overall and individual contributions, and to select the best configuration of a number of configurations for maximum level of drag reduction.

This book was released on 1974 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerodynamic drag tests were performed on a conventional cab-over-engine tractor with a 45-foot trailer and five commercially available or potentially available add-on devices using the coast-down method. The tests ranged in velocity from approximately 30 miles per hour to 65 miles per hour and included some flow visualization. A smooth, level runway at Edwards Air Force Base was used for the tests, and deceleration measurements were taken with both accelerometers and stopwatches. An evaluation of the drag reduction results obtained with each of the five add-on devices is presented.
