Crashworthiness of Side Impact Beams
… carried out into the crashworthiness of side impact beams. Two specific beams were investigated: a commercially used steel beam and a prospective composite beam made from a glass fibre weave within a polypropylene matrix. The components were simply supported and were subjected to …

Analysis of a car door subjected to side impact
… in this thesis focuses on the response of a side impact beam located in a car door to impact loading in close conformation to the Federal Motor Vehicle Safety Standard 214 (FMVSS 214) standard. The side impact beam is situated in both the front and rear side doors of a vehicle between the …

Assessment of Crash Energy - Based Side Impact Reconstruction Accuracy
… version has not previously been examined for side impacts. Given the importance of side impact crash modes and the widespread use of NASS/CDS data, an assessment of the program's reconstruction accuracy is warranted. The goal of this thesis is to quantify the accuracy of WinSMASH ?V …

Finite element simulation of the human body in vehicle side impact
Accident statistics have shown that automotive side impacts are a major safety problem. The side impact dynamics of an occupant are very complex and difficult to investigate. Industrial research has mainly focused on the impact dynamics of man-made side impact dummies, rather than on the dynamics …

Injury Metrics, Real World Crash Reconstruction, and Robust Injury Prediction for a Human Body Model in Side Impact
Motor vehicle crashes (MVCs) are a significant public health problem. Worldwide, MVCs kill over 1.2 million people each year. Improved understanding of the occupant loading conditions in real world crashes is critical for injury prevention and new vehicle design. Real world crash reconstructions …

The Biomechanics of Thoracic Skeletal Response
… injuries, and 43.3% of all AIS 5+ injuries. In side impact collisions, it has been reported that thoracic injuries are the most common type of serious injury (AIS≥3) to vehicle occupants in both near side and far side crashes which do not involve a rollover. In addition, rib fractures are the …

Validation of the Global Human Body Models Consortium Mid-Sized Male Model in Lateral Impacts and Sled Tests
… it one of the most common causes of death. Side impact injuries are particularly dangerous and present different injury patterns than those seen in frontal crashes. This implies that any kind of predictive model must not only be validated in frontal impacting scenarios, but also lateral …

Development of Pole Impact Testing at Multiple Vehicle Side Locations As Applied To The Ford Taurus Structural Platform
A test method was developed whereby repeated pole impacts could be performed at multiple locations per test vehicle, allowing a comparison of energy and crush relationships. Testing was performed on vehicles moving laterally into a 12.75 inch diameter rigid pole barrier. Crush energy absorption …

Essays on the Role of Metrics in Innovation
… process. The second essay explores the impact of introducing a new metric on the rate and direction of innovation. I study the setting of US automotive safety, finding that the introduction of the side impact dummy as a metric reduced overall fatalities but also led to disproportionate …

Development of a Comparison Technique Between Crash Tests and Real-World Crashes
… horizontal principle direction of force (PDOF) impacts was compared to a similar crash test by developing a standard protocol for comparison methods. Once a similar case was found, a comparison technique was developed for the vehicle, crash, occupant, and injury characteristics between the …

Front underride protection devices: design methodology for heavy vehicle crashworthiness
… sizing intensifies when a passenger vehicle is impacted. To improve crash safety, Front Underride Protection Devices (FUPDs) are a proposed solution to establishing a compatible collision between a passenger vehicle and a heavy vehicle. The European Union is among numerous administrations to …

The impact of localized road accident information on road safety awareness
… anti-lock braking, and passive measures, such as side impact protection, serve to mitigate the consequences of those accidents that do occur. A number of psychological phenomena, such as attribution error, explain the mixed success of road safety campaigns. Most drivers believe that they are less …

Analysis of Force-Limiting Capabilities of Football Neck Collars
… and other neck injuries due to football impacts. Transient brachial plexopathy, commonly called a stinger or burner, is an injury to the brachial plexus. As many as 65% of collegiate football players will receive suffer such an injury. Accessory neck collars are worn to mitigate the risk …

The Potential of Event Data Recorders to Improve Impact Injury Assessment in Real World Crashes
… (1) validate EDR data accuracy in full-frontal, side-impact moving deformable barrier, and small overlap crash tests; (2) evaluate EDR survivability beyond regulatory crash tests, (3) determine the seat belt accuracy of current databases, and (4) assess the merits of other vehicle-based crash …

Experimental and numerical developments in predicting the crashworthiness of Formula One composite structures
… results obtained from crash testing a real F1 Side Impact Structure (SIS). This kind of experimental data, which is usually kept confidential, can serve as a benchmark with which to assess the numerical tools. The quasi-static and dynamic crush tests of the SIS were also complemented with …
