目的以钢化玻璃为研究对象,设计安全合理的运输包装,并对其保护性能进行有限元分析。方法选择包装材料,设计运输包装各组件的结构及尺寸,利用Pro/E建立运输包装模型,利用Ansys Workbench模型进行静态堆码载荷仿真分析、模态仿真分析、随机振动仿真分析。结果通过静态堆码仿真得到等效应力最大值发生在松木托盘处,为0.506 MPa,远小于松木的屈服极限(10.47 MPa);等效应变最大值为0.0044,换算成包装件变形为2.31 mm,小于包装件允许变形量为4.2 mm;模态仿真分析得到包装件的工作频率为42.2,44.8,51.2,52.6,69.5,69.8 Hz,避开了汽车公路运输车的共振频率2 Hz和10 Hz;在随机振动仿真分析中,包装件在y方向位移为0.037 mm,远小于包装件允许变形量。结论通过仿真分析可以判定所设计的钢化玻璃运输包装方案合理,能够在运输过程中有效保护钢化玻璃的安全。

The work aims to design safe and reasonable transportation package, and conduct the finite element analysis on its protection performance, with tempered glass as the research object. Packaging materials were chosen to design the structure and size of each component of the transportation package. Pro/E was used to establish the transportation package model. The static stacking load simulation analysis, modal simulation analysis and random vibration simulation analysis were carried out with the Ansys Workbench model. The maximum equivalent stress resulting from the static stacking simulation occurred at the pine pallet, and it was 0.506 MPa and far less than the yield limit（10.47 MPa） of pine. The maximum equivalent strain was 0.0044, which was 2.31 mm converted into package deformation, and it was less than the allowable package deformation value（4.2 mm）. The modal simulation analysis showed that the operating frequency of the package was 42.2, 44.8, 51.2, 52.6, 69.5 and 69.8 Hz, which avoided the resonance frequency（2 Hz and 10 Hz） of the automobile on road. In the random vibration simulation analysis, the displacement of the package in the y direction was 0.037 mm, which was much smaller than the allowable package deformation value. Through simulation analysis, it can be determined that the designed transportation package scheme of the tempered glass is reasonable, which can effectively protect the tempered glass during transportation.
