A two-degree-of-freedom nonlinear product packaging system model was established. The impact kinetic equation was obtained and solved numerically. The rectangular impulse response characteristics of key components in the hyperbolic tangent packaging system were studied. The damage boundary surfaces of the key components are obtained by numerical solution. The influences of nominal frequency ratio, damping, pulse excitation amplitude and system parameters on the damage boundary of critical components are discussed. The results show that frequency ratio, damping, pulse excitation amplitude and system parameters Significant impact on the damaged boundary of key components, the conclusions of the study provide a scientific basis for product packaging design.
