The work aims to conduct the kinetic analysis on the packaging pad with seven degrees of freedom with respect to the four-corner cushion to lay the foundation for the simulation with such kind of pad. Matlab was used for programming to generate random Gauss white noise, and the white noise was filtered. After that, the ode15s module was used to solve the dynamic differential equation of the pad packaging system with seven degrees of freedom based on energy method. The vertical vibration displacement of all legs was consistent, with the numerical value less than 8 mm, the deflection angle displacement between 0.006 and 0.008 rad and the vertical displacement response of the package lower than 6~6.8 mm. In such case, the cushioning characteristics of the cushioning pad were verified under this working condition. Under the action of such excitation and the vibration of packaging system, the transported package is effectively protected and the simulation results are achieved through the matching of the linear trend and the measured data.
