Micromachines Free Full-Text Investigating the Effect of Grinding
High-speed rail grinding is a unique passive grinding maintenance strategy that differs from conventional grinding techniques. Its grinding behavior is dependent on the relative motion between the grinding wheel and rail; hence, it possesses great speed and efficiency. In this study, the effects of the duration of grinding time and By analyzing the influence of different grinding processes on the rail surface layer, a direct influence of grinding parameters on the rail surface layer could be identified. Increasing depth of cut a e leads to higher specific tangential grinding forces F t ′,which affect the contact area specific grinding energy E c ′′ .Influence of rail grinding process parameters on rail surface

Porous grinding wheels toward alleviating the pre-fatigue and
High-speed rail grinding stones (GS) were fabricated using zirconia alumina (ZA) with five mass ratios of F16 to F30 to explore the regulatory mechanism of abrasives with mixed granularity on the grinding performance. With the decrease of abrasive grit size, the enhanced abrasive crushing strength can control the grinding Grinding performance of graphite (C) and molybdenum disulfide (MoS 2) impregnated grinding-stone (GS) were investigated in detail.The results illustrated that abrasives pulled-out were dominated with the increase of self-lubricating fillers due to their stratified structure, which reduced the grinding amount and grinding ratio of GS.Self-lubricating filler of grinding-stone toward alleviating rail

Monitoring rail profile wear with meaningful performance
Introduction. Despite the general recognition of the benefits of adopting performance-based rail monitoring and management programmes, knowledge gaps still remain in terms of: (1) the selection of relevant indicators of rail condition and performance; (2) deterioration rates and the thresholds that trigger maintenance interventions; and (3) The grinding apparatus is presented only for the experimentation investigation of the influencing mechanism and the grinding performance of the rail material [25][26][27].(PDF) Dynamic Analysis of a Novel Rail-Grinding Car Using Open

Investigation of conditions leading to critical transitions
Rail grinding has been applied worldwide as the most common means of routine maintenance [2]. Due to the merits of compliant grinding, efficient grinding, and cold grinding compared with the traditional abrasive wheel rail grinding, abrasive belt grinding technology [3,4] has recently become a novel rail grinding method [5,6].Facing with the limitation in the application of the current main rail grinding technologies, a novel rail grinding technology based on abrasive belt grinding technology, abrasive belt rail grinding (ABRG) [4,5,6,7,8], emerged, which thanks for the rapid development in modern abrasive belt manufacturing and advanced high Experimental and simulation research on residual stress for

Influence of Rail Grinding Operations on the World's Largest Multimodal Network. 60. Rail-wheel interaction plays a key role in determining the life of railway tracks. An increase in the speed and axle load leads to significant wear and fatigue damage on materials resulting in a safety concern for the Indian Railway network.Passive grinding is a new rail grinding strategy. In this work, the influence of grinding pressure on the removal behaviors of rail material in passive grinding was investigated by using a selfA concept of adaptive control system for rail grinding

Rolling contact fatigue in relation to rail grinding ScienceDirect
Rail samples were tested under various scenarios as part of a complete analysis of the rail grinding process. Two main group of tests were performed which assessed the following: 1) preventive and corrective maintenance on fresh rail samples and 2) post-grinding tribological performance of the ground samples.The wheel/rail contact performance and curve capacity could be further improved by the optimization of the asymmetrical rail grinding target profile. In order to modify the target profile smoothly, the nonuniform rational B-spline curve with adjustable weight factors is used to establish a parameterized model of railhead curves in the Optimization of the target profile for asymmetrical rail grinding in
