文档介绍：中文题目:钢轨打磨工艺试验台载轨小车的设计
摘要:在铁路运输系统中,钢轨的使用寿命主要由磨耗和滚动接触疲劳决定,要延长钢轨的使用寿命,需要考虑钢轨制造和养护维修两个方面。具体地说,就是生产高质量钢轨,有效地润滑轮轨界面和对钢轨断面进行科学打磨。当磨损程度较轻但又影响了机车的正常行驶时,直接更换钢轨显然不合算,所以,对钢轨打磨就变得十分必要。对钢轨打磨使用的是钢轨打磨列车。钢轨打磨列车是用于消除钢轨踏面缺陷、轨头侧磨以及纵向渡磨的大型养路机械。目前,我国正在引进、消化、吸收国外先进技术的基础上逐步进行国产化研制。为此,必须研制钢轨打磨试验台,结合我国铁路钢轨材质性能与损伤特点,进行钢轨打磨的试验研究,来指导国产化钢轨打磨列车的研制。本文主要介绍了有关钢轨打磨的背景、理论、技术和应用成果,并将依据试验台所要完成的功能要求设计一沿轨道运动的载轨小车,通过对各种可能的方案进行分析,选择较优方案进行完整的载轨小车设计研究。

英文题目:The Designed of Dail Car Containing
of Technology Test Bed Rail Grinding
Abstract: In the rail transport system, the life of rail mainly decided by the wear and rolling contact fatigue. To extend the life of rail, need to consider the manufacture and maintenance of rail aspects. Specifically, is to produce high-quality rail and effective lubrication of the rail wheel-rail interface and the polished cross-section of scientific. When worn to a lesser extent but the normal running of the otive, the direct replacement of the rail is clearly uneconomical, therefore, on the rail grinding es very necessary. On the rail grinding train using a rail grinding. Rail grinding train is used to remove rail surface defects, cephalic and vertical crossing rail grinding mill of large road maintenance machinery. At present, China is develop gradually domestically on the basis of the introduction, digestion and absorption of foreign advanced technology. This paper describes the background about the rail grinding, theory, technology and application of the results, and test-bed based on the functional requirements to be plished by designing a set along the track rail car movement, through the analysis of all possible options, select the optimum Program contains plete design of rail cars.
Keywords: maintenance machinery,rail grinding,rail car containing,gear.
