| 摘 要： | 通过建立并分析二自由度的包装系统数学模型,提出了三次非线性包装系统关键部件在运输过程中破损边界曲面的评价方法。通过数学分析方法对三次非线性包装系统动力学方程进行求解,得到了破损边界曲线和破损边界曲面。运用数值分析分别讨论了破损边界受频率比、脉冲激励幅值和阻尼的影响规律。为运输包装的材料选择和结构设计提供了依据。

| Abstract: | Two-degree-of-freedom mathematical model of packaging system was established and analyzed.A damage evaluation method of a cubic nonlinear packaging system with critical component was put forward.Dynamical equations of the cubic nonlinear packaging system were solved by mathematical analysis.Based on the analysis,the damage boundary curve and damage boundary surface of critical component was obtained.The effect of frequency ratio,damping ratio,and pulse amplitude on the damage boundary of critical component was discussed.The purpose was to provide reference for material selection and structural design of transport package. |
