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.

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.

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.

Book excerpt: The analysis of a traffic accident requires additional knowledge that is not normally taught during the university education. Therefore, the analysis of road accidents usually is performed by specialized experts. The knowledge required for this was published in the early 80s in a previous German edition of this book. Now a team of authors created the long overdue update. The authors are experts in their field and make their knowledge available in a contemporary representation. In this computer-aided methods of work are taken into accountas as well.

Available in PDF, EPUB and Kindle. Book excerpt: The increasing number of fatalities and injuries in motor vehicle accidents highlights the importance of studying occupants' response during collisions; specifically, the head and neck due to their vulnerability. In this research program, we study the occupant kinematic response and kinetic behavior during frontal, rear and lateral motor vehicle collisions. In view of its severity and commonality, rear-end collisions leading to whiplash, have been given additional attention. The work, which is conducted analytically, numerically and experimentally, is divided into four integrated sections. First, an analytical multibody dynamics model (MBD) of the head and the neck was developed to determine the head response during simulated frontal, lateral and rear impacts. Second, extensive nonlinear dynamic finite element (FE) simulations were carried out to study the occupant response in the aforementioned impact scenarios using detailed vehicle and occupant numerical models. Third, a novel head-neck prototype was developed to experimentally validate the newly developed MBD and FE models. Fourth, a novel shock absorber was developed using foam-filled frusta. The FE simulations were extended to examine a number of safety strategies, involving seat belt, head restraint, airbag and shock absorber on the occupant response during rear-end collisions. The outcomes of this work provide greater understanding of occupants' neck injury mechanism in vehicle collisions. Our results further reveal that in frontal impacts, the capsular ligament (CL) and the interspinous ligament (ISL) are vulnerable to injury, while in lateral collisions, the highest ligament elongation was reported for the CL, exceeding a stipulated injury threshold. In rear-end collisions, the anterior longitudinal ligament was at risk of injury, as well as the ISL and the CL during neck flexion. Our work reveals that the frontal airbag plays an important role in preventing excessive neck flexion in rear impact, and that the newly proposed shock absorber can lead to improved occupant safety. Additionally, it further shows that the experimentally developed head-neck 3D printed prototype response is in good agreement with the MBD and FE predictions. The prototype can be used as the core for developing head-neck models in future anthropomorphic test dummies.
