Improving the repeatability and reproducibility of belt fit measurement with 6YO and 10YO ATDs
In previous work, researchers at the University of Michigan Transportation Research Institute (UMTRI) developed a method for quantifying the belt fit provided by belt-positioning boosters by measuring the belt location relative to the six- and ten-year-old Hybrid-III dummies. In another study, the...
Understanding work task assessment sensitivity to the prediction of standing location
Digital human models (DHM) are now widely used to assess worker tasks as part of manufacturing simulation. With current DHM software, the simulation engineer or ergonomist usually makes a manual estimate of the likely worker standing location with respect to the work task. In a small number of...
BioTab a new method for analyzing and documenting injury causation in motor-vehicle crashes.
Objective: To describe a new method for analyzing and documenting the causes of injuries in motor vehicle crashes that has been implemented since 2005 in cases investigated by the Crash Injury Research Engineering Network (CIREN). Methods: The new method, called BioTab, documents injury causation...
Influence of object weight and terminal orientation on upper limb postures during grasping, holding, and placing cylindrical object
This study examines the effect of object weight and terminal orientation on upper limb postures during grasping, holding, and placing cylindrical objects. An experiment including two sessions was conducted. In the first session, eight subjects grasped and held a horizontally located cylindrical...
A pilot study of biomechanical factors affecting upper limb posture during grasping, holding, and placing cylindrical object
A biomechanical analysis was performed to explain upper limb postures during grasping, holding, and placing cylindrical objects. This study is needed for ergonomic design of work equipment and methods to provide workers with sufficient control over objects in object transfer tasks.
Comparison of WorldSID and cadaver responses in low-speed and high-speed nearside impact
A series of lateral impact tests was performed in which the WorldSID midsize-male crash-test dummy was struck with a segmented padded impactor that separately loaded the thorax, abdomen, iliac wing, greater trochanter, and mid thigh. Tests were conducted using 8 m/s and 3 m/s initial impact...
Design and testing of a child restraint for developing countries using low-technology manufacturing methods
As passenger car use becomes more common in developing countries, the number of child passengers killed and injuries also increases. Rates of child restraint use appear to be much lower in developing countries than in the U.S. or Europe. One barrier to increased restraint use is the relatively high...
Development, validation, and application of a parametric pediatric head finite element model for impact simulations
In this study, a statistical model of cranium geometry for 0- to 3-month-old children was developed by analyzing 11 CT scans using a combination of principal component analysis and multivariate regression analysis. Radial basis function was used to morph the geometry of a baseline child head finite...
