Available in PDF, EPUB and Kindle. Book excerpt: In order to understand an occupant's often violent and complicated motion during rollover accidents, the motion of an anthropomorphic dummy was predicted dynamically using the Articulated Total Body model, a human body gross motion simulation program. The accuracy of the predicted motion was established by its favorable comparison to that recorded on high speed film during a 60 mph crash in which the vehicle rolled over four times. This vehicle motion was then modified to six other rollover crash situations for computer simulation. Significant changes in the predicted occupant motion were readily observed. Differences were also observed in occupant accelerations and impact and belt forces. Keywords: Computer simulation, Modeling, Biodynamics.

Download or read book Rollover Accident Reconstruction written by Nathan A Rose and published by SAE International. This book was released on 2018-08-07 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: According to the National Highway Traffic Safety Administration, “of the nearly 9.1 million passenger car, SUV, pickup and van crashes in 2010, only 2.1% involved a rollover. However, rollovers accounted for nearly 35% of all deaths from passenger vehicle crashes. In 2010 alone, more than 7,600 people died in rollover crashes.” Rollover accidents continue to be a leading contributor of vehicle deaths. While this continues to be true, it is pertinent to understand the entire crash process. Each stage of the accident provides valuable insight into the application of reconstruction methodologies. Rollover Accident Reconstruction focuses on tripped, single vehicle rollover crashes that terminate without striking a fixed object. Topics featured in this book include: • Analysis methods through various accident phases, including advanced simulation • Vehicle event data recorder usage • Occupant ejection during rollover crash The goal of this title is to break down the various phases of a rollover crash to analyze each stage for use in the reconstruction process - to the greater understanding of crash analysts, consultants and safety engineers alike.

Available in PDF, EPUB and Kindle. Book excerpt: Collision Reconstruction Methodologies - Volume 6C - The last ten years have seen explosive growth in the technology available to the collision analyst, changing the way reconstruction is practiced in fundamental ways. The greatest technological advances for the crash reconstruction community have come in the realms of photogrammetry and digital media analysis. The widespread use of scanning technology has facilitated the implementation of powerful new tools to digitize forensic data, create 3D models and visualize and analyze crash vehicles and environments. The introduction of unmanned aerial systems and standardization of crash data recorders to the crash reconstruction community have enhanced the ability of a crash analyst to visualize and model the components of a crash reconstruction. Because of the technological changes occurring in the industry, many SAE papers have been written to address the validation and use of new tools for collision reconstruction. Collision Reconstruction Methodologies Volumes 1-12 bring together seminal SAE technical papers surrounding advancements in the crash reconstruction field. Topics featured in the series include: • Night Vision Study and Photogrammetry • Vehicle Event Data Recorders • Motorcycle, Heavy Vehicle, Bicycle and Pedestrian Accident Reconstruction The goal is to provide the latest technologies and methodologies being introduced into collision reconstruction - appealing to crash analysts, consultants and safety engineers alike.

Download or read book Simulations of Rollover Tests written by and published by . This book was released on 1988 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The motion of an occupant during a rollover crash is often Violent and complicated. This motion needs to be studied so as to determine how best to protect an occupant during a rollover crash, and the best tool known is computer models which simulate the motion of an occupant. It was the Air Force's Articulated Total Body (ATB) model which was used. The accuracy of the simulations by this model has to be determined through a limited number of rollover crash tests. Five such tests were conducted under this program using a specially designed rollover test device, and the corresponding simulations of the motion of a dummy occupant are presented. The accuracy of the simulations obtained for these five tests with a rollover test device and the similar accuracy for one full-scale crash test conducted earlier on a different testing program provide confidence that an occupant's motion during a rollover crash, whether belted or unbelted, can be satisfactorily simulated by the Air Forces ATB.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a computational, three-dimensional biodynamic model of a vehicle-occupant, crash-victim during rollover accident. The model represents the human body by a series of connected bodies simulating the limbs, torso, head and neck of the human frame. The computer algorithms are developed using DYNACOMBSC̈ a three-dimensional multibody dynamics computer simulation model. DYNACOMBS provides a dynamic analysis of arbitrary collections of bodies allowing for both translation and rotation between adjacent bodies. The relative orientation of adjacent bodies is defined by Euler parameters to avoid computational problems of singularities, which occur with other orientation angles (such as Bryan angles or Euler angles). Thus there are distinct computational advantages of the presented model over other crash-victim simulators. The governing dynamical equations for the model are based upon Kaneis̄ equations and their associated kinematical quantities (partial velocities, partial angular velocities, generalized speeds, and lower body arrays). Formulations based upon Kaneis̄ equations are believed to be the most efficient and most reliable of the various methods available for studying large multibody systems. Consequently they are ideally suited for studying the dynamics of crash victims. The developed vehicle and victim model allows for arbitrary vehicle motion. Specifically, given the vehicle rollover motion, as would occur in an accident environment, the simulation predicts the vehicle occupant movement and the forces exerted on the occupant by the seat and seat belts. The model is validated by a series of recently recorded sets of experimental data from dummies and cadavers in a variety of vehicle crash conditions.

This book was released on 2012-12-06 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: A systematic treatment of current crashworthiness practice in the automotive, railroad and aircraft industries. Structural, exterior and interior design, occupant biomechanics, seat and restraint systems are dealt with, taking account of statistical data, current regulations and state-of-the-art design tool capabilities. Occupant kinematics and biomechanics are reviewed, leading to a basic understanding of human tolerance to impact and of the use of anthropometric test dummies and mathematical modelling techniques. Different types of restraining systems are described in terms of impact biomechanics. The material and structural behaviour of vehicle components is discussed in relation to crash testing. A variety of commonly used techniques for simulating occupants and structures are presented, in particular the use of multibody dynamics, finite element methods and simplified macro-elements, in the context of design tools of increasing complexity, which can be used to model both vehicles and occupants. Audience: An excellent reference for researchers, engineers, students and all other professionals involved in crashworthiness work.
