A three-dimensional mathematical model of a seat, occupant(s), and restraint system was developed for use in aircraft crashworthiness analysis. Programs SOM-LA (Seat/Occupant Model - Light Aircraft) and SOM-TA (Seat/Occupant Model - Transport Aircraft) combine a lumped parameter model of aircraft occupants with a finite element model of the seat structure. The intent of these programs is to aid in evaluation of the performance of aircraft seat and restraint systems in crash environments. Four different cases are described, and the listing of input data is presented for each.
