| Abstract: | It is more precise to predigest the packaged products as a double degree freedom system.By applying the Runge-Kutta method,the effect of dropping height,damping,frequency ratio,mass ratio to the fragile's reaction of cushioning packaging material was discussed based on Matlab.This concept and the results have important value in the design of cushioning packaging. |
