VALIDATION OF THE CRASH VICTIM SIMULATOR VOLUME 2, ENGINEERING MANUAL--PART II: VALIDATION EFFORT

A combined analytical and experimental research project was carried out to develop and examine the validity of an improved version of the computer program used to simulate the three-dimensional dynamic gross motion responses of motor vehicle crash victims. Among the improvements incorporated in the new (CVS-IV) version of the program are a more efficient integration technique, a routine to automatically position a seated occupant in equilibrium, and modifications of the input and output control routines that make it easier to use the program. Measurements of a Part 572 50th percentile male anthropomorphic dummy were made to define an input data set for a simulation model of the dummy. Dynamic pendulum impact tests of dummy sub-assemblies were performed and modeled with the computer program. Detailed comparisons of predicted system responses with those measured in special impact sled tests of the dummy restrained by a three-point restraint belt and by pre-inflated air bag are also presented.
