中文摘要:
      目的 在国家大力发展集装箱多式联运的背景下,研究20 ft(1 ft=304.8 mm)35 t敞顶集装箱的卷钢运输方式,根据卷钢的不同规格设计2类卷钢座架并分析验证其强度性能。方法 利用SolidWorks软件建立座架三维模型,利用Ansys Workbench软件分析座架在静载与冲击条件下的位移与应力变化,然后进行静载与冲击试验,依据《铁路货物装载加固规则》与《机车车辆强度设计及试验鉴定规范车体第2部分:货车车体》规定,对仿真结果与试验结果进行比较分析。结果 在静载与冲击工况下,仿真分析结果的位移与应力均不超过结构材料的最大许用值;试验结果前后座架状态完好,未发生明显损伤变形等情况;2类座架仿真分析结果与试验结果的最大绝对偏差仅为20.19 MPa和22.23 MPa,表明仿真分析结果具有较大精度。结论 设计的20 ft 35 t敞顶箱卷钢运输座架模型设计合理,强度符合规范要求,能够满足卷钢安全高效的运输需求。
英文摘要:
      The work aims to study the coil steel transportation mode of 20 ft (1 ft=304.8 mm) 35 t open top containers under the background of China's great efforts to develop container multimodal transportation, design two types of coil steel frames according to different specifications of coil steel, and analyze and verify their strength performance. The SolidWorks software was used to establish a three-dimensional model of the frames. The Ansys Workbench software was used to analyze the displacement and stress changes of the frames under static load and impact conditions, and then the static load and impact tests were carried out. According to "Reinforcement Rules for Railway Cargo Loading" and "Strength Design and Test Accreditation Specification for Rolling Stock-Car body-Part 2:Car Body of Freight Wagons", the simulation results were compared with the test results. The displacement and stress deformation of the simulation results did not exceed the maximum allowable value of structural materials under static load and impact conditions. The test results showed that the front and rear frames were in good conditions without obvious damage and deformation. The maximum absolute deviation between the simulation analysis results and the test results of these two types of frames was only 20.19 MPa and 22.23 MPa, indicating that the simulation analysis results had great accuracy. The model of 20 ft 35 t open top coil steel transport frame designed in this work is reasonable. Its strength is in line with the specification requirements and can meet the needs of safe and efficient transportation of coil steel.
