BIODYNAMICAL PROBLEMS RELATED TO TRANSPORTATION VEHICLES--DIGITAL SIMULATION OF OCCUPANTS

Several parallel efforts are underway to develop and use dynamic occupant simulation computer programs in automobile and aircraft crashworthiness research. This paper reports upon a study funded by the Office of Naval Research evaluating five well known occupant simulation programs. Evaluation factors include numerical integration techniques, mathematical accuracy, computing time, and occupant belt and seat modeling. Additional factors evaluated are graphical output quality, readability of output, usage of documentation, and coding quality. A set of program design specifications was developed concurrently which, if followed by current researchers, should eliminate most of the numerical and user-oriented problems encountered with current occupant simulation programs. Finally, a program structure which is designed for fast turnaround studies is described. The key element in this structure is on-line graphics, which provides a rapid visual summary of the completed results.
