Dropping shock response of corrugated paperboard cushioning packaging system

In this paper, a dynamic model was proposed for a corrugated paperboard cushioning packaging system. The variational iteration method was applied and the multiplier was identified. The approximate solution for the nonlinear equations was obtained and compared with the numerical simulation results with ordinary differential equation solver in MATLAB, showing good agreement. Then resonance conditions were obtained, which should be avoided in the cushioning packaging design.
