Decision-making Scheme for Integrated Wheel-rail Intelligent Maintenance of EMUs
The quality of wheel-rail profile compatibility directly affects the operation safety and comfort of EMU.In view of problems such as unclear positioning of onboard abnormal vibration fault sources and difficulty in maintenance decision orientation during operation,relying on the intelligent HSR 2.0 scientific and technological project and based on the fusion of multi-source data such as onboard vibration data,trackside monitoring and detection data and line characteristic data,this paper studies and proposes a strategic technical scheme for integrated intelligent O&M of wheels and rails based on decision tree and random forest method,thus laying the groundwork for guiding the wheel reprofiling and replacement or rail grinding on site.
