Abstract
The paper presents a procedure for nonlinear model identification of automotive seat cushion structure. In this paper, two nonlinear models are presented. Tests show that the automotive seat cushion structure is a nonlinear system. The transfer functions obtained from the test data between the seat butt and the seat track show that the magnitude and frequency shift will be smaller as the input is increased. The models predict the transfer functions having the same trend as the results from the tests. The models are quite useful for the analysis other car structures and also provide guidance in the design of seat cushions.
