Development of a Dynamic Aircraft Seat Analysis Capability

The development of a dynamic aircraft seat analysis is presented in this paper. This analytical model is a nonlinear finite element model composed of a seat frame and cushion, restraint system, glare shield and a rigid body model of a 50^th percentile Hybrid-II anthropomorphic test dummy (ATD) occupant. Results from this analytical model are correlated with empirical results obtained during a full-scale dynamic test. The analysis is representative of the dynamic test.
