A three-dimensional mathematical model of a seat, occupants, and restraint system has been developed for use in transport aircraft crashworthiness analyses. The finite element seat model can accommodate large displacements, nonlinear material behavior, and local buckling of tubular elements. Provision for simulation of floor warping has also been included. One, two, or three passengers can be simulated. The model of each passenger consists of twelve segments whose dimensions and inertial properties have been determined from studies of human body anthropometry and from measurements of anthropomorphic dummies. The dynamic test of a three-passenger seat, modified to include an energy-absorbing capability, is described, and test data are compared with computer simulation results.
