【Abstract】 According to the data measured from the test on corrugated board, and considering the damage property of materials, the basic characteristics of the corrugated board’s cushioning property are summed up in this paper. Moreover, a nonlinear model of corrugated board is established. Nonlinear model parameters of corrugated board are identified on the basis of test data, which are gained from continuous fall shock under combination conditions of height of drop, thickness of cushion and static stress. The comparison between dynamics calculation and test results shows that this model can better represent the properties of corrugated board packaging cushion’s acceleration, velocity, displacement, absorbing property of shock energy, plastic deformation and so on. Using this model, the cushioning package structures for products can be designed.更多还原
