Abstract: In order to solve the problem of negative volume and long computation time caused by large deformation of aviation
seat cushion in the impact simulation of aviation seat finite element models, a lumped parameter model of aviation
seat cushion consisting of parallel nonlinear springs and linear damping is proposed. Firstly, the static and dynamic
compression test of the aviation seat cushion material is carried out, and the finite element model and the lumped
parameter model of the aviation seat cushion are established respectively. Secondly, the spring damping parameters
of the lumped parameter model are fitted according to the results of finite element simulation, and the dynamic re鄄
sponses of the two models are compared under 14, 16 and 19 g delta pulses. The results show that the consistency
between the two models is good, and the lumped parameter model of the aviation seat cushion established in this
paper can provide support for the simplification of the complex finite element model containing the seat cushion.

Key words: aviation seat cushion, lumped parameter model, static and dynamic compression test, finite element model
