| 摘要: |
| 目的 研究易碎品在运输包装过程中不同防护材质缓冲包装结构的防护性能。方法 通过Ansys Workbench中的模态分析（Modal）和随机振动分析模块（Random Vibration），对模型进行模态和随机振动仿真分析，得到易碎品的各向应力、位移、总应力等，分析对比2种防护材质的仿真结果，选取最优的缓冲方案，并进行随机振动和跌落实验。结果 2种防护材质下缓冲结构都具有良好的防护性能，选择设计的EPE缓冲结构更具有经济环保性，且在随机振动和跌落试验中，包装件没有发生变形和损坏，内容物完好。结论 为易碎品低成本、高可靠性的结构设计提供了思路，也为产品性能的预测和运输方案的检测提供了一种分析手段。 |

| Abstract: |
| The work aims to study the protective performance of cushioning packaging structures made of different protective materials during the transportation and packaging of fragile products. Through modal analysis and random vi-bration analysis module in Ansys Workbench, the modal and random vibration simulation analyses of the model were carried out to obtain all-directional stress, displacement and total stress of fragile products. The simulation results of two kinds of protective materials were analyzed and compared, the optimal cushioning scheme was selected, and the random vibration and drop tests were carried out. The cushioning structures made of two protective materials had good protective performance, and it was more economic and environmental to select the designed EPE cushioning structure. Moreover, there was no deformation or damage to the package during random vibration and drop tests. It is concluded that ideas have been provided for low cost and high reliability structural design of fragile products, and an analysis method is also provided for product performance prediction and transportation plan detection. |
