| Abstract: |
| Cushioning model of two degrees of freedom for expanded polyethylene cushioning packaging system was established. The shock response spectrum of the nonlinear system under the action of half-sine pulse was calculated using Runge-Kutta method. The influencing rule of parameter λ-1,λ-2, and λ-3 on shock response spectrum was discussed. |
| Key words: expanded polyethylene cushioning packaging shock response spectrum |
