Packaging system dynamics model for C-flute corrugated board was established based on dynamics constitutive model. In the C-flute corrugated cardboard's cushioning packaging system, the effects of different damp, linear, sinusoidal and tangent parameters on shock spectrum and damage boundary of vulnerable part of C-flute corrugated cardboard packaging were researched, which were produced by shocks from rectangular waves. The research was conducted under the concept of three-dimensional shock spectrum and damage boundary surface, with application of the Rnuge-Kutta algorithm. The results showed that cushion performance of C-flute corrugated cardboard is restricted by damping coefficient, linear, sinusoidal and tangent parameters and has a significant influence on shock spectrum and damage boundary of C-flute corrugated cardboard's cushioning packaging system.
