Experimental Research of Rail Grinding Quantity
INTERNATIONAL JOURNAL ON Advances in Information Sciences and Service Sciences, 2013Experimental research of rail grinding quantity with single grinding wheel has been implemented on GMC-96 rail grinding train in this paper. Firstly, this paper put forward a new idea that rail grinding quantity is defined as the cross-sectional area difference between the profile curves of pre-grinding and post-grinding, Secondly，because of ...

Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2018
The objective of this study is to explore the influence of grinding stone granularity on the grinding force and rail material removal behaviors using a rail grinding friction machine. The results indicate that with the increase in granularity, the grinding force, and friction coefficient in the grinding interface obviously increase, which brings about ...

Optimized Rail Grinding Through Dynamic Positioning and Powering of Grinding Motors
2016 Joint Rail Conference, 2016Rail grinding has become a widely accepted practice in the railroad industry to not only remove surface defects but to also shape the head of the rail to achieve a specific wheel/rail contact interface. Optimal wheel/rail contact is paramount for a variety of reasons including (but not limited to): reduced rail wear and fatigue defects with associated ...

Modeling the development of rail corrugation to schedule a more economical rail grinding
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2019Rail corrugation should be managed appropriately, as it causes noise, vibration, and degradation of track components and materials. Generally, rail corrugation is managed with the removal of rail surface roughness by rail grinding. However, in many cases, rail corrugation will reoccur after the rail is ground, thereby making the management of the ...

Study on automatic alignment algorithm in rail grinding of rail head profile
2017 IEEE 2nd Advanced Information Technology, Electronic and Automation Control Conference (IAEAC), 2017Rail profile alignment algorithm determines the amount of rail-grinding, the distribution of grinding heads, and directly affects the final grinding effect. The alignment algorithm based on the rail waist profile has been proposed. The paper studied the high accurate and automatic alignment algorithm based on the rail head profile.

Grinding induced martensite on the surface of rails [PDF]
, 2014 Rolling contact fatigue (RCF) is causing crack initiation and crack propagation in rails. Some types of RCF cracks are found to be associated with a white etching layer (WEL). A metallurgical investigation was carried out on a worn rail and the amounts of WEL at different positions on the rail were determined.

Machining rails by means of an end grinding wheel
Russian Engineering Research, 2011The nonuniform cutting properties of the tool’s working surface are considered in plane grinding by the end of a wheel. A method is proposed for increasing the productivity without changing the composition of the abrasive or modernizing the equipment.
