Development of a Promising Universal Thoracic Trauma Prediction Methodology 780891

Analysis of experimental acceleration time history data obtained from a thoracic instrumentation array has been performed. The data were generated under test conditions which include realistic frontal impacts in belt, air bag, and steering column systems and side impacts with rigid and padded door structures. Data from frontal and lateral pendulum impacts were also included.The results demonstrate that the instrumentation array captures sufficient information from the impact event to allow prediction of resulting thoracic trauma, defined either as thoracic AIS or total number of thoracic fractures, using a single function for each injury measure.Each function is universal in the sense that it is valid for all test modes and directions of impact.A strategy for developing a surrogate thorax to implement this injury predictive methodology is discussed and preliminary specifications are presented.
