The Prediction of Thoracic Impact Injuries 760822

This paper presents the concepts and first group of test results from a project designed to:
  1. 1.
    Quantify thoracic impact response using cadaver and baboon subjects;*
  2. 2.
    Compile analytical functions relating thoracic kinematic response to injuries observed in the experiments; and,
  3. 3.
    Define performance specifications insuring response fidelity between human and surrogate thoraxes. The experiments, which vary G-level, velocity, and direction of impact, utilize restraint systems including belts, airbags, and EA-columns. Resulting injuries are recorded at autopsy and an AIS rating assigned. Using the kinematic accelerometer data, injury-predictive functions are generated using statistical regression procedures. The utilization of project results in developing performance specifications for surrogate thoraxes is discussed in conclusion.
