According to the measured data from static and dynamic flat compression tests on B flute double wall corrugated fiberboard cushion, the three basic characteristics of the corrugated fiberboard's flat compression cushioning and other features are summed up in the paper. Based on the construction of the static model, the nonlinear viscoelastic plastic model of the cushion is established. which can overall reflect the dynamic responses of the cushion under repeated flat compression drop shocks at various conditions. The establishment of the model and successful identification of its parameters not only solve the problem of dynamic calculation of the flat compression cushion, which creates necessary conditions for the optimal design of shockproof packaging, but also solve the problem of great amount of test work. Only a few times of tests are needed to identify the model's parameters and to know completely the cushioning performance of the flat compression corrugated paperboard.
