Concepts, Terms and Definitions Related to Surrogate Measures of Safety

2018-01-12
WIP
J3166
The document will define and describe in condensed form the fundamental theoretical concepts of surrogate measures of safety and define indicators (with variations). To the extent possible, the definitions should be kept neutral with respect to the technology or data collection method used as these change rapidly.

Comparing Dolly Rollover Testing to Steer-Induced Rollover Events for an Enhanced Understanding of Off-Road Rollover Dynamics

2011-11-01
The field of motor vehicle rollover research and testing has been one of multiple and varied approaches, dating back to at least the 1930's. The approach has been as simple as tipping a vehicle over at the top of a steep hill ( Wilson et al., 1972 ), to as complex as releasing a vehicle from an elevated roll spit mounted to the rear of a moving tractor and trailer ( Cooper et al., 2001 and Carter et al., 2002 ).

Using STPA During Development and Safety Assessment of Civil Aircraft

2018-02-13
WIP
AIR6913
This AIR will provide a basic understanding of STPA and how it can be applied to development and safety assessment of civil aircraft. It will explain, by way of an example, the information needed to begin STPA, the expected STPA outputs, and the phases of aircraft development and safety assessment that can be supported by STPA.

Mitigation for Loss-of-Control Accidents in Transport Airplanes

2010-08-12
WIP
ARP6149
Prevention of catastrophic upset mishaps cannot depend solely on recovery training. The proposed document should complement the training initiatives already in place. As a committee dealing with transport human factors and handling qualities, the output must consider both issues. At the same time, we cannot ignore initial and recurrent training issues and the widespread use of ground-based simulators. The plan would follow the approach taken in the 2003 S-7 white paper but would extend the scope to all forms of LOC, not just repeated rudder reversals. As with the white pa-per, the new document would have sections on transport handling qualities, flight control modes, aircraft displays, simulator requirements, and approval for IFR test evaluations as well as covering training issues. This new document would complement, not replace documents such as the Airplane Upset Recovery Training Aid.

Development and Evaluation of a Human Lower Extremity Model

2001-06-04
2001-06-0049
A finite element model of the human lower extremity has been developed in this study to simulate lower extremity behavior in frontal car crashes. Precise geometry of the human lower extremity and material properties of the hard and soft tissues were introduced to the model. The performance of the model was evaluated by comparing with dynamic loading test data using post mortem human subjects (PMHS). The comparison proved its ability to estimate dynamic responses of the human lower extremity. A study was conducted using the model to investigate possible factors of loading to the ankle and tibia. Force and moment were calculated with different time history profiles of footwell intrusion and pelvis motion. The results suggested that timing of maximum intrusion was important as well as its magnitude. It was also found that loading to the tibia could be affected not only by intrusion but also by pelvis motion.

Innovative Rear Air Blower Design Application for Improving Cabin Thermal Comfort with Improved Air Distribution and Air Quality

2020-08-18
2020-28-0034
In recent times, overall thermal comfort and air quality requirement have increased for vehicle cabin by multifold. To achieve increased thermal comfort requirements, multiple design innovation has happened to improve HVAC performance. Most of the advance features like multizone HVAC, dedicated rear HVAC, Automatic climate control, advance air filters, and ionizers etc. lead to increase in cost, power consumption, weight, and integration issues. Besides this in the vehicle with only front HVAC, airflow is not enough to meet rear side comfort for many cars in the B/C/SUV segment. This study aims to analyze the various parameters responsible for human thermal comfort inside a car. The focus of study is to use light weight, low power consumption, compact Rear Blower to provide passengers comfort by providing optimum airflow inline of mean radiant temperatures and cabin air temperature.

Occupant and Vehicle Responses in Rollovers

2004-03-08
During the past decade, there has been a steady increase in studies addressing rollover crashes and injuries. Though rollovers are not the most frequent crash type, they are significant with respect to serious injury and interest in rollovers has grown with the introduction of SUVs, vans, and light trucks. A review of Occupant and Vehicle Responses in Rollovers examines relevant conditions for field roll overs, vehicle responses, and occupant kinetics in the vehicle. This book edited by Dr. David C. Viano and Dr. Chantal S. Parenteau includes 62 technical documents covering 15 years of rollover crash safety, including field crash statistics, pre- and rollover dynamics, test procedures and dummy responses.

Neck Injury Biomechanics

2009-08-03
This book includes 40 noteworthy papers covering more than 15 years (1993 to 2009) of research on the biomechanics of neck injuries. "Although much of the underlying testing was vehicle-related," writes editor Jeffrey A. Pike, "the resultant data regarding neck motion and loading are applicable to a broad range of injury scenarios." In addition to numerous SAE papers, Neck Injury Biomechanics includes papers from the National Highway Traffic Safety Administration's International Technical Conference on the Enhanced Safety of Vehicles (ESV), the Stapp Car Crash Conference, and the International Conference on the Biomechanics of Impact (IRCOBI), as well as articles from Traffic Injury Prevention. The book also includes an introductory background section that ties together concepts of anatomy, injuries, and radiographic imaging so that the research featured in the book will be more readable and useful to a wide range of safety professionals.

Event Data Recorders

2008-04-01
This book contains 28 landmark papers, providing a comprehensive look at event data recorder (EDR) technology for cars, light trucks, and heavy vehicles. By collecting EDR data, vehicle safety trends can be established, providing car companies, researchers, and regulators with science-based methods to better understand vehicle crashes. In addition to classic and cutting-edge papers, the book features insightful materials on the new National Highway Traffic Safety Administration (NHTSA) Final Rule on Event Data Recorders (49 CFR, Part 563), including the rule itself, a summary, and the response to petitions for reconsideration.
