Abstract：Abstract: The critical components of bar type in muti-freedom cushioning packaging products were likely to damage and cause system failures during the work, so this paper proposed that the item of cushioning packaging products were assumed to be rigid components, the critical components of bar type were processed into uniform and elastic parts, and nonlinear coupling dynamics models between the critical component and item were established as well as motion differential equations. The results of nonlinear cushioning packaging system were obtained by difference method. It demonstrated that the maximum acceleration of the bar component occured at its free end, whose stress was minimum. The bar end of the critical component had the maximum stress and minimum acceleration. Whether the maximum stress of the bar was beyond the proportion of elastic components was an effective parameter to determine whether the item lose its functions.
