Description

technical field [0001] The invention relates to the technical field of rail transit wheel-rail lubrication detection, in particular to a fluorescence detection method and a detection device for detecting the coating effect of a rail top friction modifier. Background technique [0002] When the train passes the curve, problems such as corrugation, side grinding, rolling contact fatigue, and noise caused by the lateral movement of the wheel set are the key points and difficulties that need to be solved urgently in the field of rail transit operation and maintenance technology. In recent years, the successful application of friction modifiers has broken people's concept that "railtops cannot be lubricated". Field and laboratory studies have shown that by applying friction modifiers to the wheel-rail interface, the traction and braking performance of the train can be improved. To improve the bending ability of the train, it can effectively control various diseases of the wheel-r...
