This book was released on 2016 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant advancements in enhancing passenger safety and vehicle structures have been made in the automotive industry to protect the occupants and to minimize the injuries during crash events. Variety of crash tests, based on federal regulatory standards, have been performed with an end goal to examine the occupant kinematics and potential injury responses. Among different automotive crash scenarios, the frontal impact is the most common type of accident, which has been considered in this study. In recent years, computer-aided engineering tools have been extensively utilized in modeling, analysis and design of vehicle structures and occupant safety systems. The primary reason for the development and use of simulation models is to reduce the number of full-scale sled tests performed, which require vast flow time and are associated with significant cost. This thesis entirely focuses on the comparison of dynamic responses of human body models versus the crash dummy models in various vehicle frontal federal regulatory standards. For this reason, a ford taurus car representing a typical sedan has been considered as a medium. The simulation tests are conducted for the full frontal impact, small offset overlap impact and oblique impact configurations. A car interior environment is developed in MADYMO code, in which the human and dummy models are placed in. The acceleration acquired from the finite element analysis of frontal crash scenarios and the driver seat node are then input into the MADYMO code for both human and dummy models, and their kinematic responses are then compared. Per regulations, chest injury is considered to be a prominent factor in frontal crashes. Hence, the variations of chest deflection, chest acceleration and viscous criteria are investigated. The results from this study illustrate the potential difference between the human and dummy dynamic performances in various frontal crash scenarios. In particular, the differences in chest acceleration, chest deflection, and flexibility of spine are quantified.

This book was released on 2017 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this thesis is to develop a computational human musculoskeletal model to investigate the change in the kinematic behavior of the model's lower extremities under the influence of activated (active) and deactivated (passive) muscles during a representation frontal collision using OpenSim software. Since OpenSim is seldom used in crash simulations, an appropriate model evaluation is performed by comparing the model's kinematics, obtained from the OpenSim's inverse dynamic simulation, against LS-DYNA's explicit non-linear side impact simulation of a finite element model for a car-pedestrian collision. The required musculoskeletal model is constructed in OpenSim and scaled to meet the requirements of the Hybrid III 50th Percentile crash test dummy. For evaluating the developed model, the kinematics from both programs (OpenSim and LS-DYNA), containing identical displacement data, is compared by visual observation of identical time frames. Using the evaluated model in the forward dynamics domain of OpenSim, a representative frontal crash simulation is conducted for the active and passive muscle states of the model, and the kinematic difference in its lower extremities is observed and compared. The results were also compared to MADYMO's human body model simulations conducted under similar conditions. This study indicates that the role of the muscle activation on the human body responses during a car collision is important. The novel technique developed and utilized in this study is shown to be quite useful in modeling and simulation of a car occupant's real kinematic response during a car collision.

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.

Download or read book Transport Planning and Traffic Safety written by Geetam Tiwari and published by CRC Press. This book was released on 2018-09-03 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recognition of the importance of road safety as a major health issue, the World Health Organization has declared 2011-2021 the Decade of Safety Action. Several countries in Europe, North America, and Asia have been successful in reducing fatalities and injuries due to road traffic crashes. However, many low-income countries continue to experience high rates of traffic fatalities and injuries. Transport Planning and Traffic Safety: Making Cities, Roads, and Vehicles Safer offers a source book for road safety training courses as well as an introductory textbook for graduate-level courses on road safety taught in engineering institutes. It brings together the international experiences and lessons learned from countries which have been successful in reducing traffic crashes and their applicability in low-income countries. The content is based on lectures delivered during an international course on transportation planning and traffic safety, sponsored annually by the Transportation Research and Injury Prevention Programme (TRIPP) at the Indian Institute of Technology, Delhi. The book is interdisciplinary and aimed at professionals—traffic and road engineers, vehicle designers, law enforcers, and transport planners. The authors examine trends in performance of OECD countries and highlight the public health and systems approach of traffic safety with the vulnerable road user in focus. Topics include land use (transportation planning, mobility, and safety), safety education and legislation, accident analysis, road safety research, human tolerance to injury, vehicle design, safety in construction zones, safety in urban areas, traffic calming, public transportation, safety laws and policies, and pre-hospital care of the injured.

This book was released on 2018-08-27 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aviation safety can be greatly enhanced by the expeditious use of computer simulations of crash impact. Unlike automotive impact testing, which is now routine, experimental crash tests of even small aircraft are expensive and complex due to the high cost of the aircraft and the myriad of crash impact conditions that must be considered. Ultimately, the goal is to utilize full-scale crash simulations of aircraft for design evaluation and certification. The objective of this publication is to describe "best practices" for modeling aircraft impact using explicit nonlinear dynamic finite element codes such as LS-DYNA, DYNA3D, and MSC.Dytran. Although "best practices" is somewhat relative, it is hoped that the authors' experience will help others to avoid some of the common pitfalls in modeling that are not documented in one single publication. In addition, a discussion of experimental data analysis, digital filtering, and test-analysis correlation is provided. Finally, some examples of aircraft crash simulations are described in several appendices following the main report.Fasanella, Edwin L. and Jackson, Karen E.Langley Research CenterAIRCRAFT SAFETY; NONLINEARITY; FINITE ELEMENT METHOD; AIRCRAFT ACCIDENTS; COMPUTERIZED SIMULATION; CRASHES; IMPACT TESTS; AIRCRAFT DESIGN; AUTOMOBILES; CERTIFICATION; CORRELATION; COSTS; FLIGHT SAFETY...
