A mathematical model of a transport aircraft seat, occupants, and restraint system has been developed for use in analysis of transport aircraft crashworthiness. Because of the significant role played by the seat in overall system crashworthiness, a finite element model of the seat structure is included. The seat model can accomodate large plastic deformations and includes the capability for simulation of local buckling of bending members. Because the program has been written for use primarily by engineers concerned with the design and analysis of seat and restraint systems, an effort has been made to minimize the input data required to describe the occupant. This report is Volume I of a two-volume document. Volume I discusses development of the mathematical model of the occupants, the finite element seat analysis, validation, and organization of the computer program. Volume II contains instructions for preparing input data and operating the program.
