把缓冲包装系统简化为了两自由度线性系统，将系统运动微分方程变换为了无量纲形式，然后写成矩阵形式的状态方程，借助Matlab/Simulink动态仿真工具构建了包装系统的仿真模型，分析了包装系统受迫振动和跌落冲击响应，并讨论了与质量比、阻尼比、频率比、跌落高度等因素的关系。可避免不必要的破坏性试验，为优化运输包装设计提供理论依据。

The cushioning package was predigested as a double degree-of-freedom system. The movement differential equations were transformed into dimensionless equations and then state equations in form of matrix. By using Matlab/Simulink, the simulation models were established. The forced vibration and drop response of cushioning package were analyzed. And the relationships between the response and mass ratio, damping ratio, frequency ratio, dropping height were discussed. The simulation can avoid unnecessary destructive tests and provide theoretical basis for optimizing cushioning package.
