基于SolidWorks和Ansys的20 ft集装箱石材运输架设计

Design of Stone Transport Rack Suitable for 20 ft Container Based on SolidWorks and Ansys

目的为解决石材在长距离运输过程中,存在不易加固、破损率高、运输成本昂贵等问题,设计一款安全、轻便、可循环使用、可拆解、便于回送的20 ft(1 ft=0.3048 m)集装箱石材运输架。方法首先按照《铁路货物装载加固规则》要求,计算作用在石材上的各种力,确定装载加固方案,再根据《钢结构设计规范》及20 ft通用集装箱内部结构确定石材运输架的材料与规格,然后采用SolidWorks对运输架进行三维建模,利用Ansys对模型进行有限元分析。结果分析得出,石材运输架最薄弱部分应力分别为155.36,99.56,99.48,70.87,343.75 MPa,位移变形量分别为0.54,1.95,0.60,0.01,0.10 mm,均符合规定。结论20 ft集装箱石材运输架运输效率高,可实现“门到门”运输,应用前景良好,对当下石材运输发展有较大影响。

In order to solve the problems of difficult reinforcement,high damage rate and high transportation cost during the long distance transportation of stone,and to design a new type of safe,light,recyclable,disassembled,and easy to return stone transportation rack.First,various forces acting on the stone is calculated in accordance with the require-ments of the"Railway Freight Loading Reinforcement Rules"to determine the loading and reinforcement scheme,and then the material and specifications of the stone transport rack is determined according to the"Standard for Design of Steel Structures"and the internal structure of the 20 ft general container.SolidWorks is used to carry out three-dimensional modeling of the transportation rack,and Ansys is used to perform finite element analysis on the model.The result analysis shows that the stress of the weakest parts of the stone transport rack are 155.36,99.56,99.48,70.87,343.75 MPa,and the displacements are 0.54,1.95,0.60,0.01,0.10 mm.The stone transportation rack has high transportation efficiency and can realize"Door-to-Door"transportation,and has good application prospects,which has great impact on the current development of stone transportation.
