【摘要】：随着莱钢磁悬浮列车轨排项目被列入建设部的“十一五”国家科技支撑计划，莱钢集团与中国南车集团合作研发的磁悬浮列车轨排取得了突破性成果，突破了轨排的热轧瓶颈，实现了F型轨排的批量生产，目前莱钢磁悬浮列车轨排项目，可实现年产中低速磁悬浮轨排系列产品10万吨。中国第一辆中低速磁悬浮列车，，在由莱钢建安公司建设的唐山1.5公里F轨排试验线上，安全运行100天，标志着磁悬浮列车运行试验成功。莱钢集团研发的此项目具备显著的自主创新优势，包括了技术专利10项，制定国家和行业标准7项，正在完善着具备高技术含量、自主创新、自主知识产权的中低速磁悬浮列车轨排技术体系。 F型磁悬浮轨排的热轧批量生产，给磁悬浮轨道交通的发展奠定了坚实基础。要实现磁悬浮轨道交通的大规模建设，仍然需要突破弯轨制作、轨枕量产加工、轨排矫直、轨排安装等关键技术。本课题以实现F型轨排的大规模建设为目标，立足生产实际中遇到的问题，致力于F型轨排的矫直，解决F型钢热轧成形后的几何尺寸缺陷。本文是依据矫直机的生产过程和工作原理，首先从矫直机的总体方案评述开始，依次进行了主电机的选择计算，主传动系统的设计，工作辊与支承辊设计，矫直机压下与压上装置的设计与校核；并对矫直机的某些零件和基本结构进行了设计；并且研究了矫直机的发展方向。在设计完成后利用UG NX8.0软件建立矫直模型，并使用软件自带的仿真程序进行有限元仿真，利用仿真结果对模型进行优化设计，同时使用通用有限元软件MSC.Marc进行力学仿真，将两者结果进行比较，验证UG仿真结果，使设计更加完善。
[Abstract]:With the project of maglev train rail row of Laigang being included in the "11th Five-Year Plan" of the Ministry of Construction, the maglev train rail platoon developed by Laigang Group and China South car Group has made a breakthrough, breaking through the bottleneck of hot rolling of rail line. The mass production of F type rail platoon has been realized. At present, the project of maglev train in Laiwu Iron and Steel Company can realize the annual production of 100,000 tons of medium and low speed maglev train series. The first medium and low speed maglev train in China is the first medium and low speed maglev train. On the 1.5-kilometer F rail line of Tangshan built by Jianan Company of Laiwu Iron and Steel Co., the safe operation for 100 days marks the success of the maglev train operation test. The project developed by Laigang Group has significant advantages of independent innovation. It includes 10 technical patents, 7 national and industrial standards, and is improving the technical system of rail drainage for medium and low speed maglev trains with high technology content, independent innovation and independent intellectual property rights. The hot rolling mass production of F type maglev rail row has laid a solid foundation for the development of maglev rail transit. In order to realize the large-scale construction of maglev rail transit, it is still necessary to break through the curved rail production, mass production of sleeper, and straighten the rail line. The aim of this project is to realize the large-scale construction of F type rail platoon. Based on the problems encountered in production practice, this project is devoted to straightening out F type rail platoon and solving the geometric dimension defect after hot rolling of F type steel. According to the production process and working principle of the straightening machine, the selection calculation of the main motor, the design of the main transmission system, the design of the work roll and the back-up roll are carried out in turn, starting with the general plan of the straightening machine. The design and verification of the pressing and pressing device of the straightener, the design of some parts and the basic structure of the straightener, and the development direction of the straightener are also studied. After the design is finished, the straightening model is established by UG NX8.0 software, and the finite element simulation is carried out by using the software's own simulation program. The model is optimized by the simulation results, and the mechanical simulation is carried out by using the universal finite element software MSC.Marc. Compare the two results, verify the UG simulation results, make the design more perfect.
