Validation of the human motion simulation framework posture prediction for standing object transfer tasks.
The Human Motion Simulation Framework is a hierarchical set of algorithms for physical task simulation and analysis. The Framework is capable of simulating a wide range of tasks, including standing and seated reaches, walking and carrying objects, and vehicle ingress and egress. In this paper,...
Quantifying dynamic mechanical properties of human placenta tissue using optimization techniques with specimen-specific finite-element models
Motor-vehicle crashes are the leading cause of fetal deaths resulting from maternal trauma in the United States, and placental abruption is the most common cause of these deaths. To minimize this injury, new assessment tools, such as crash-test dummies and computational models of pregnant women,...
Simulating complex automotive assembly tasks using the HUMOSIM framework
Efficient methods for simulating operators performing part handling tasks in manufacturing plants are needed. The simulation of part handling motions is an important step towards the implementation of virtual manufacturing for the purpose of improving worker productivity and reducing injuries in...
Dynamic performance of child restraints with two-point belt securement
Three different models of forward-facing CRS were evaluated dynamically using a two-point belt fixation (FMVSS 213 Standard). Ann additional test was conducted with one same model of CRS but using the three-point belt fixation. Results showed that CRS performance differ strongly according to belt...
Evaluation of the static belt fit provided by belt-positioning booster seats
Belt-positioning booster seats are recommended for children who use vehicle seat belts as primary restraints but who are too small to obtain good belt fit. Previous research has shown that belt-positioning boosters reduce injury risk, but the belt fit produced by the wide range of boosters in the...
Anthropometric specification of child crash dummy pelves through statistical analysis of skeletal geometry
The pelves of the child dummies of the widely used Hybrid-III family are based on minimal data from children. Because an accurate pelvis design is critical for realistic assessments of belt restraint interactions, an analysis of medical imaging data was conducted to develop guidance for improved...
An optimization approach to occupant safety and fuel economy in vehicle design
A major challenge in automotive design is the creation of safe vehicles with minimal environmental impact. This study presents a modeling framework for evaluating and optimizing body designs for improved occupant safety and fuel efficiency. Vehicle body mass is considered as the main link between...
Development of new criteria for assessing the risk of knee-thigh-hip injury in frontal impacts using hybrid III femur force measurements
Injury patterns in real-world frontal crashes and the forces predicted in computational simulations of knee impacts suggest that the risk of hip injury is higher than the risk of knee/distal femur injury in most frontal crashes that are similar in severity to those used in FMVSS 208 and NCAP....
