Book Synopsis Crashworthiness of Transportation Systems: Structural Impact and Occupant Protection by : Jorge A.C. Ambrósio
Download or read book Crashworthiness of Transportation Systems: Structural Impact and Occupant Protection written by Jorge A.C. Ambrósio and published by Springer Science & Business Media. 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.
Book Synopsis Biodynamic Modeling and Analysis of Motor Vehicle Rollover Occupants by :
Download or read book Biodynamic Modeling and Analysis of Motor Vehicle Rollover Occupants written by and published by . This book was released on 2004 with total page pages. 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.

Book Synopsis Development of a Multi-wall Virtual Environment and Implementation of Vehicle Model for a Driving Simulator by : Sumanth Raghavendra
Download or read book Development of a Multi-wall Virtual Environment and Implementation of Vehicle Model for a Driving Simulator written by Sumanth Raghavendra and published by . This book was released on 2006 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This thesis describes the construction of a low-cost, four-wall immersive driving simulator that can perform motions similar to a road vehicle. A driving simulation is a good example of applications that utilize a dynamic model in a simulated environment. Such simulations can be decomposed into a graphic model responsible for rendering a specific space-configuration of entities within a virtual world as well as a dynamic model responsible for determining the evolution of this configuration over time. This thesis attempts to address some important aspects of building these two models, with an emphasis on their cooperation. To build the simulator car this study concentrates on the integrative methods of evaluating a dynamic vehicle model. The virtual environment development is accomplished by using Level of Detail (LOD) application. The experiments prove that the designed simulator is adequate in performing some realistic vehicle effects as discussed in the thesis"--Abstract, leaf iii.

Book Synopsis Automotive Side-impact Simulations and Comparison of Dummy and Human Body Model Crash Dynamic Responses According to Regulatory Standards by : Durga Venkata Suresh Koppisetty
Download or read book Automotive Side-impact Simulations and Comparison of Dummy and Human Body Model Crash Dynamic Responses According to Regulatory Standards written by Durga Venkata Suresh Koppisetty and published by . This book was released on 2017 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: According to the U.S. Department of Transportation, National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety (IIHS), side-impact car accidents are the second leading cause of fatalities in the United States. Compared to all other accidents, side-impact crashes are quite dangerous to the occupants because of their limited ability to absorb the crash energy and less space for intrusion. NHTSA and IIHS have developed safety standards to prevent fatalities by conducting several experiments using anthropomorphic test dummies (ATDs). Although the regulations are based on the use of crash dummies, there might be differences between actual human crash performance and dummy crash performance. In recent years, technology has improved in such a way that crash scenarios can be modeled in various computational software, and human dynamic responses can be studied using active human body models, which are a combination of rigid bodies, finite elements, and kinematic joints, thus making them flexible to use in all crash test scenarios. In this research, nearside occupants were considered because they are more likely to be injured in a side-impact crash. Vehicle side-impact crash simulations were carried out using LS-DYNA finite element (FE) software, and the occupant response simulations were conducted with Mathematical Dynamic Models (MADYMO) software. Because the simulation of an entire FE model of a car and occupant is quite time consuming and expensive, a prescribed structural motion (PSM) technique was utilized and applied to the side-door panel with an occupant positioned in the driver seat of the car using the MADYMO code. Regular side-impact deformable barrier and pole test simulations were performed with belted and unbelted occupant models considering two different target vehicles—a mid-size sedan and a small compact car. Responses from dummy and human body models were compared in order to quantify the noticeable differences between the two performances in nearside-impact accidents.
