【摘要】：隨著萊鋼磁懸浮列車軌排項目被列入建設(shè)部的“十一五”國家科技支撐計劃，萊鋼集團與中國南車集團合作研發(fā)的磁懸浮列車軌排取得了突破性成果，突破了軌排的熱軋瓶頸，實現(xiàn)了F型軌排的批量生產(chǎn)，目前萊鋼磁懸浮列車軌排項目，可實現(xiàn)年產(chǎn)中低速磁懸浮軌排系列產(chǎn)品10萬噸。中國第一輛中低速磁懸浮列車，，在由萊鋼建安公司建設(shè)的唐山1.5公里F軌排試驗線上，安全運行100天，標志著磁懸浮列車運行試驗成功。萊鋼集團研發(fā)的此項目具備顯著的自主創(chuàng)新優(yōu)勢，包括了技術(shù)專利10項，制定國家和行業(yè)標準7項，正在完善著具備高技術(shù)含量、自主創(chuàng)新、自主知識產(chǎn)權(quán)的中低速磁懸浮列車軌排技術(shù)體系。 F型磁懸浮軌排的熱軋批量生產(chǎn)，給磁懸浮軌道交通的發(fā)展奠定了堅實基礎(chǔ)。要實現(xiàn)磁懸浮軌道交通的大規(guī)模建設(shè)，仍然需要突破彎軌制作、軌枕量產(chǎn)加工、軌排矯直、軌排安裝等關(guān)鍵技術(shù)。本課題以實現(xiàn)F型軌排的大規(guī)模建設(shè)為目標，立足生產(chǎn)實際中遇到的問題，致力于F型軌排的矯直，解決F型鋼熱軋成形后的幾何尺寸缺陷。 本文是依據(jù)矯直機的生產(chǎn)過程和工作原理，首先從矯直機的總體方案評述開始，依次進行了主電機的選擇計算，主傳動系統(tǒng)的設(shè)計，工作輥與支承輥設(shè)計，矯直機壓下與壓上裝置的設(shè)計與校核；并對矯直機的某些零件和基本結(jié)構(gòu)進行了設(shè)計；并且研究了矯直機的發(fā)展方向。 在設(shè)計完成后利用UG NX8.0軟件建立矯直模型，并使用軟件自帶的仿真程序進行有限元仿真，利用仿真結(jié)果對模型進行優(yōu)化設(shè)計，同時使用通用有限元軟件MSC.Marc進行力學(xué)仿真，將兩者結(jié)果進行比較，驗證UG仿真結(jié)果，使設(shè)計更加完善。
[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.
