Download or read book Computational Modeling and Analysis of a Passenger Car Frontal Impact Per New FMVSS Offset Oblique and Small Overlap Tests written by Sagun Shrestha and published by . This book was released on 2015 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crash tests play a vital role in the design and development of new vehicles to ensure customer safety. The results obtained from the test programs such as the ones from the National Highway Traffic Safety Administration (NHTSA) are useful for further development of vehicles pertaining to consumer safety. The new and latest oblique offset and small overlap crash tests represent more realistic configurations of the frontal car impact accidents compared to earlier version of standards. In this study, finite element (FE) models of a family sedan car impact surroundings are utilized to reconstruct the tests. The objective of this study is to utilize computational modeling and analysis techniques to assess the performance of a typical sedan car per new small overlap frontal crash test and oblique offset tests, and to compare the results with the original rigid barrier impact crash test in terms of physical intrusion of the vehicle body parts and examining the corresponding potential injuries to occupants. The validation of the models are performed to ensure model accuracy and to check for any abnormalities in the FE models. In this research, the vehicle-to-barrier and vice versa models are simulated using the LS-DYNA nonlinear code. The full frontal impact crash tests are simulated according to the NCAP protocol. The oblique offset and small offset frontal impact tests are then investigated as they represent real-world scenarios better. The data obtained from the intrusions on the vehicle's A- and B- pillars, firewall, toe pan, knee bolster and steering column are analyzed. The results from different scenarios obtained are then compared in terms of intrusion and acceleration inside the car and the analysis of intrusion and occupant injury. It is observed that the small offset crash test adds more challenge not only to the structure of the vehicle but also to the design of seat belts and airbags. This study indicates that the compliance with the offset oblique and small offset frontal impact tests provide the best occupant protection where the occupant sustains maximum G- force especially in terms of head impact protection to the car's A-pillar.

Available in PDF, EPUB and Kindle. Book excerpt: Automotive Accident Reconstruction: Practices and Principles introduces techniques for gathering information and interpreting evidence, and presents computer-based tools for analyzing crashes. This book provides theory, information and data sources, techniques of investigation, an interpretation of physical evidence, and practical tips for beginners. It also works as an ongoing reference for experienced reconstructionists. The book emphasizes three things: the theoretical foundation, the presentation of data sources, and the computer programs and spread sheets used to apply both theory and collected data in the reconstruction of actual crashes. It discusses the specific requirements of reconstructing rollover crashes, offers background in structural mechanics, and describes how structural mechanics and impact mechanics are applied to automobiles that crash. The text explores the treatment of crush energy when vehicles collide with each other and with fixed objects. It delves into various classes of crashes, and simulation models. The framework of the book starts backward in time, beginning with the analysis of post-crash vehicle motions that occurred without driver control. Applies time-reverse methods, in a detailed and rigorous way, to vehicle run-out trajectories, utilizing the available physical evidence Walks the reader through a collection of digital crash test data from public sources, with detailed instructions on how to process and filter the information Shows the reader how to build spread sheets detailing calculations involving crush energy and vehicle post-crash trajectory characteristics Contains a comprehensive treatment of crush energy This text can also serve as a resource for industry professionals, particularly with regard to the underlying physics.

Download or read book Assessment of Fuel Economy Technologies for Light Duty Vehicles written by National Research Council and published by National Academies Press. This book was released on 2011-06-03 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various combinations of commercially available technologies could greatly reduce fuel consumption in passenger cars, sport-utility vehicles, minivans, and other light-duty vehicles without compromising vehicle performance or safety. Assessment of Technologies for Improving Light Duty Vehicle Fuel Economy estimates the potential fuel savings and costs to consumers of available technology combinations for three types of engines: spark-ignition gasoline, compression-ignition diesel, and hybrid. According to its estimates, adopting the full combination of improved technologies in medium and large cars and pickup trucks with spark-ignition engines could reduce fuel consumption by 29 percent at an additional cost of $2,200 to the consumer. Replacing spark-ignition engines with diesel engines and components would yield fuel savings of about 37 percent at an added cost of approximately $5,900 per vehicle, and replacing spark-ignition engines with hybrid engines and components would reduce fuel consumption by 43 percent at an increase of $6,000 per vehicle. The book focuses on fuel consumption-the amount of fuel consumed in a given driving distance-because energy savings are directly related to the amount of fuel used. In contrast, fuel economy measures how far a vehicle will travel with a gallon of fuel. Because fuel consumption data indicate money saved on fuel purchases and reductions in carbon dioxide emissions, the book finds that vehicle stickers should provide consumers with fuel consumption data in addition to fuel economy information.

Download or read book Structural Impact written by Norman Jones and published by Cambridge University Press. This book was released on 2011-12-26 with total page 605 pages. Available in PDF, EPUB and Kindle. Book excerpt: Structural Impact is concerned with the behaviour of structures and components subjected to large dynamic, impact and explosive loads which produce inelastic deformations. It is of interest for safety calculations, hazard assessments and energy absorbing systems throughout industry. The first five chapters introduce the rigid plastic methods of analysis for the static behaviour and the dynamic response of beams, plates and shells. The influence of transverse shear, rotatory inertia, finite displacements and dynamic material properties are introduced and studied in some detail. Dynamic progressive buckling, which develops in several energy absorbing systems, and the phenomenon of dynamic plastic buckling are introduced. Scaling laws are discussed which are important for relating the response of small-scale experimental tests to the dynamic behaviour of full-scale prototypes. This text is invaluable to undergraduates, graduates and professionals learning about the behaviour of structures subjected to large impact, dynamic and blast loadings producing an inelastic response.
Download or read book The Automotive Body written by L. Morello and published by Springer Science & Business Media. This book was released on 2011-03-04 with total page 685 pages. Available in PDF, EPUB and Kindle. Book excerpt: “The Automotive Body” consists of two volumes. The first volume produces the needful cultural background on the body; it describes the body and its components in use on most kinds of cars and industrial vehicles: the quantity of drawings that are presented allows the reader to familiarize with the design features and to understand functions, design motivations and fabrication feasibility, in view of the existing production processes. The second volume addresses the body system engineer and has the objective to lead him to the specification definition used to finalize detail design and production by the car manufacturer or the supply chain. The processing of these specifications, made by mathematical models of different complexity, starts always from the presentations of the needs of the customer using the vehicle and from the large number of rules imposed by laws and customs. The two volumes are completed by references, list of symbols adopted and subjects index. These two books about the vehicle body may be added to those about the chassis and are part of a series sponsored by ATA (the Italian automotive engineers association) on the subject of automotive engineering; they follow the first book, published in 2005 in Italian only, about automotive transmission. They cover automotive engineering from every aspect and are the result of a five-year collaboration between the Polytechnical University of Turin and the University of Naples on automotive engineering.

Download or read book Energy Absorption of Structures and Materials written by G Lu and published by Elsevier. This book was released on 2003-10-31 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important study focuses on the way in which structures and materials can be best designed to absorb kinetic energy in a controllable and predictable manner. Understanding of energy absorption of structures and materials is important in calculating the damage to structures caused by accidental collision, assessing the residual strength of structures after initial damage and in designing packaging to protect its contents in the event of impact. Whilst a great deal of recent research has taken place into the energy absorption behaviour of structures and materials and significant progress has been made, this knowledge is diffuse and widely scattered. This book offers a synthesis of the most recent developments and forms a detailed and comprehensive view of the area. It is an essential reference for all engineers concerned with materials engineering in relation to the theory of plasticity, structural mechanics and impact dynamics. - Important new study of energy absorption of engineering structures and materials - Shows how they can be designed to withstand sudden loading in a safe, controllable and predictable way - Illuminating case studies back up the theoretical analysis
