二自由度线性系统跌落响应影响因素分析

Study on the Influencing Factors of Dropping Response of Double Degree Freedom Linear System

把运输包装件简化为两自由度系统,基于M atlab,运用四阶龙格-库塔法对具有线性弹性材料的缓冲包装系统进行数值分析,分别讨论了跌落高度、阻尼比、频率比、质量比对主体及易损件位移及加速度响应的影响;该方法和结论对缓冲包装设计具有重要意义。

It is more precise to predigest the packaged products as a double degree freedom system. By applying the Runge - Kutta method, the effect of dropping height, damping, frequency ratio, mass ratio to the fragile＇s reaction of cushioning packaging material was discussed based on Matlab. This concept and the results have important value in the design of cushioning packaging.
