Shock Response Analysis of Key Components of Cushion Packaging System

It can be seen in Figure 5a that when the mass ratio is constant, the damping ratio ξ1 has a greater impact on the maximum acceleration of key components. It can be seen from Figure 5b that the frequency has a greater effect on the maximum acceleration of the critical components. When the system frequency ratio is less than 0.75, the maximum acceleration response of the key components increases with the increase of the damping ratio ξ1; when the system frequency ratio is greater than 0.75, the maximum acceleration response value of the key components with the damping ratioξ1 The increase is smaller.

In combination with Figure 5a and Figure 6a, the maximum acceleration response of the key component decreases with the increase of the damping ratio ξ2, and the maximum force velocity response of the key component increases with the increase of the damping ratio ξ1. Figure 6b shows that when the system frequency ratio is less than 1, the maximum acceleration response of key components gradually decreases as the damping ratio ξ2 increases; and when the system frequency ratio is greater than 1, the maximum acceleration response of key components increases with the damping ratio ξ2. After the first drop, it rises and becomes larger with the damping ratio ξ2.

4 Conclusion

In this paper, the drop impact equation of buffer packaging system based on the response of key components is established, and the fourth-order Runge-Kutta method is used for numerical analysis. The displacement, velocity and acceleration of drop impact can be easily found in language loop filling of MATLAB. Response curve, and further analysis of various parameters of the system on the impact of the maximum acceleration of key components for the actual buffer packaging design provides a reference and theoretical basis.
