This paper first establishes the model for a 2-DOF non-linear cushion packaging system with strong hysteresis and then derives its vibration equations. The vibration equations are transformed into ones using dimensionless variables and parameters. The influence of mass ratio and stiffness ratio on the system under excitation of trapezoidal pulse shock has been analyzed based on the response spectra obtained by applying the fourth order Runge-Kuntta method to the transformed equations. Results show that the mass ratio is the key design parameter.
