目的 针对铁路运输玻璃的过程，存在包装成本高、效率低、破损率高等问题，设计一种安全稳定、结构简单、可重复循环使用、可拆解的铁路20 ft（1 ft=0.3028 m）玻璃平台式集装箱。方法 制定算例装载加固方案，使用SolidWorks软件对玻璃平台式集装箱进行实体建模和有限元分析，按照集装箱强度和变形量的技术要求，进行可承载的载荷极限计算。最后，将平台式集装箱裸包装玻璃分别与木箱包装形式、公路运输方式进行包装成本、运输成本比较。结果 分析得出，玻璃垂向载荷应力最薄弱环节为275.0 MPa；吊起时，最薄弱环节应力为254.3 MPa，纵向载荷应力最薄弱环节为288.5 MPa；各方向应力均小于Q345低合金钢的许用应力（345 MPa）。垂向载荷位移最薄弱环节变形量为5.358 mm；吊起时，最薄弱环节变形量为5.876 mm，纵向力位移变形量为5.156 mm，各方向位移变形量均合理。从经济角度分析，平台式集装箱裸包装玻璃运输成本最小、包装成本最低。结论 文中设计的铁路20 ft玻璃平台式集装箱市场前景可观，可极大地提高玻璃运输效率，降低物流成本。

In view of the process of transporting glass by rail, there are problems such as high packaging cost, low ef-ficiency and high damage rate. The work aims to design a kind of safe, stable, reusable and detachable railway 20 ft glass platform container with a simple structure. The loading and reinforcement scheme was formulated. The SolidWorks software was used to perform solid modeling and finite element analysis on the glass platform container, and carry out the load limit calculation according to the technical requirements of the container strength and deformation. Finally, the platform container’s bare packaging glass was compared with the wooden box packaging form and the road transportation mode in terms of the packaging cost and transportation cost. The analysis showed that, the weakest link of the vertical load stress of glass was 275.0 MPa; during hoisting, the weakest link stress was 254.3 MPa; the weakest link of longitudinal load stress was 288.5 MPa; and the stress in all directions was less than the allowable stress of Q345 low alloy steel (345 MPa). The weakest link deformation of vertical load displacement was 5.358 mm; during hoisting, the weakest link deformation was 5.876 mm; the deformation of longitudinal force displacement was 5.156 mm; and the displacement deformation in all directions was reasonable. From the economic point of view, the platform container’s bare packaging glass had the lowest transportation cost and the lowest packaging cost. The railway 20 ft glass platform container designed herein has a promising market prospect, which can greatly improve the glass transportation efficiency and reduce the logistics cost.
