Appropriate analysis of CIREN data using NASS-CDS to reduce bias in estimation of injury risk factors in passenger vehicle crashes.
The Crash Injury Research Engineering Network (CIREN) database contains detailed medical and crash information on a large number of severely injured occupants in motor vehicle crashes. CIREN's major limitation for stand-alone analyses to explore injury risk factors is that control subjects...
A stochastic visco-hyperelasitc model of human placenta tissue for finite element crash simulations
Placental abruption is the most common cause of fetal deaths in motor-vehicle crashes, but studies on the mechanical properties of human placenta are rare. This study presents a new method of developing a stochastic viscohyperelastic material model of human placenta tissue using a combination of...
Development and testing of a more realistic pelvis for the hybrid III 6-year-old ATD
Objective: Design and test a new pelvis for the Hybrid III 6-year-old (6YO) anthropometric test device (ATD) with a more humanlike bone structure, flesh contour, and flesh stiffness intended to provide more realistic interaction with belt restraints. Methods: Target geometry for the new pelvis bone...
Effects of vehicle features on CRS installation errors
This report documents a study of how vehicle features contribute to CRS installation errors. Thirty-two subjects were recruited based on their education level (low or high) and experience with installing CRS (none or experienced). Each subject was asked to perform four child restraint installations...
Labels, instructions and features of convertible Child Restraint Systems (CRS) evaluating their effects on CRS installation errors.
This report documents a study of how CRS features, labels, and instructions contribute to CRS installation errors. Task 1A focused on assessing different physical features of 16 convertible CRS, while Task 1B evaluated baseline and modified versions of labels and instructions for two CRS models....
Evaluation of Hybrid-III 6YO ATD chest jacket shape and position
In previous work, belt fit on the Hybrid-III six-year-old (6YO) anthropomorphic test device (ATD) was found to depend on the positioning of the chest jacket of the ATD. Moreover, differences were noted between jackets manufactured by Denton-ATD and First Technology Safety Systems (FTSS). The...
A study of the difference between nominal and actual hand forces in two-handed sagittal plane whole-body exertions
Given a task posture, changes in hand force magnitude and direction with regard to joint locations result in variations in joint loads. Previous work has quantified considerable vertical force components during push/pull exertions. The objective of this work was to quantify and statistically model...
