落地镜缓冲包装设计及仿真分析

目的 基于落地镜的物理特性和运输环境，采用SolidWorks软件建立包装件模型，设计一款满足多款式落地镜使用的包装产品，并提供一种新的包装设计思路。方法 应用Ansys Workbench软件对模型进行仿真，完成模态分析和随机振动仿真分析，应用Ansys Workbench内置的显示动力学插件进行包装件的跌落仿真分析，检验设计的合理性和可行性。结果 对比分析结果可知，新包装件受到冲击时的变形量远小于旧包装件的变形量，且分布均匀，落地镜受其影响而破损的概率极低。在跌落仿真中，旧包装件中落地镜铝合金下边框受到的等效应力为42.158 MPa，大于玻璃镜子的许用应力(28 MPa)，导致包装件中的落地镜破损;在新包装件中，铝合金下边框受到的应力小于28 MPa，落地镜不会发生破损。结论 文中设计的落地镜蜂窝纸板箱加聚乙烯泡沫的包装箱具有合理性，其防护性能不仅优于原包装箱，且适用范围更广，证明该设计思路可行。

Design and Simulation Analysis of Floor Mirror Buffer Packaging

The work aims to establish a packaging model through SolidWorks software based on the physical characteristics and transportation environment of floor mirrors, design a packaging product that meets the needs of multiple styles of floor mirrors, and provide a new packaging design concept. Ansys Workbench software was used to simulate the model, complete modal analysis and random vibration simulation analysis, and the built-in display dynamics plugin of Ansys Workbench was used to conduct drop simulation analysis of packaging components, to verify the rationality and feasibility of the design. The comparative analysis results showed that the deformation of the new packaging under impact was much smaller than that of the old packaging, and the distribution was uniform. The probability of the floor mirror being damaged due to its influence was extremely low. In the drop simulation, the equivalent stress on the aluminum alloy lower frame of the floor mirror in the old packaging was 42.158 MPa, which was greater than the allowable stress of the glass mirror of 28 MPa, which could cause damage to the floor mirror in the packaging. In the new packaging, the stress on the aluminum alloy lower frame was less than 28 MPa, and the floor mirror will not be damaged. In conclusion, the design of the floor mirror honeycomb cardboard box and polyethylene foam packaging box in this paper is reasonable. It not only has protective performance better than the original packaging box, but also has a wider scope of application, which proves that the design idea is feasible.
