Scalable Multi-Purpose Virtual Human Model for Future Safety Assessment 2014-01-0534
The paper concerns the development of a new scalable virtual human body model. The model has been developed to assess safety risk during various complex crash scenarios including impacts from different directions. The novel approach described couples the basic multi-body structure with deformable segments, resulting in short calculation time. Each multi-body structure segment carries the particular surface parts that are linked to the segment with non-linear springs representing the behavior of related soft tissues.
The response of particular body segments (head, thorax, pelvis, lower extremities) is validated in known impact scenarios and the response of the model is tuned to the experimental corridors obtained from literature. The tuning process involved the adjustment of both model material and numerical parameters in order to get the correct response for all the tests. Several energy level impacts from different directions are usually considered in order to generalize the model; to test its robustness and correct biofidelic performance.
The model is designed modularly to be simply adopted towards the pre-defined height, age and mass. The developed model is useful for the robust design of vehicles and transportation infrastructure of various sectors of transport means.
