摘　　要：为适应白货产品物流特点,满足铁路白货运输需求,开发大容积内陆集装箱作为载运器具。根据铁路限界要求和铁路主要集装箱运输车辆的装载能力,确定新型大容积通用内陆集装箱的长度为50 ft,最大总重为36 t。在满足铁路限界和铁路平车车辆宽度的基础上,分析集装箱横截面可采用的2种设计方案——直角矩形横截面和变截面横截面。计算2种设计方案的集装箱最大内容积,最终选择集装箱横截面为变截面梯形的设计方案。对选定的设计方案进行超限校核,计算结果表明:集装箱横截面底部矩形部分及顶部梯形部分均满足铁路限界要求。分析研究集装箱的主要结构并进行轻量化设计,在此基础上,进行有限元分析计算。该型集装箱已经开始投入使用,有效助力了铁路现代物流体系的建设。In order to adapt to the logistics characteristics of white goods products and meet the demand for white goods transportation by railways,large-volume inland containers have been developed as carrying devices.According to the requirements of railway clearance and the loading volume of main railway vehicles for container transportation,the length of the new large-volume general inland container was determined to be 50 ft,and the maximum total weight was 36 t.After meeting the railway clearance and the width of railway flat cars,two design schemes for the cross-section of the container were analyzed:a right-angle rectangular cross-section and a variable cross-section.The maximum internal volume of the container in the two design schemes was calculated,and the design scheme with a variable cross-section trapezoid was ultimately selected.The selected design scheme was checked for over-limit,and the calculation results show that the rectangular part at the bottom and the trapezoidal part at the top of the container cross-section both meet the railway clearance requirements.The main structure of the container was studied,and a lightweight design was carried out.On this basis,finite element analysis and calculation were performed.This type of container has been put into use,effectively facilitating the construction of a modern railway logistics system.
