Modeling of Commuter Category Aircraft Seats Under Crash Loading 2003-01-3028

This paper describes the development of a non-linear finite element model of a commuter category aircraft seat designed to explore the issue of energy absorption in severe, but survivable, crashes. Using a reference seat, the paper presents a description of the model and the results of finite element modeling of the seat at increasingly severe impact velocities. The paper presents the results of a parallel experimental program, conducted to validate the model, in which instrumented crash dummies were drop tested in the reference seat at the same impact velocities as the simulation. Experimental results are reported for passenger lower lumbar loading, peak pelvic acceleration, and seat structural loading.
