By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-From Washington, D.C., NewsRx journali sts report that a patent application by the inventors Liang, Shulin (Chengdu, CN ); Liu, Xiaolong (Chengdu, CN); Wen, Zefeng (Chengdu, CN); Xiao, Xinbiao (Chengd u, CN), filed on November 4, 2022, was made available online on June 6, 2024. No assignee for this patent application has been made. News editors obtained the following quote from the background information suppli ed by the inventors: "Rail wave wear (referred to as rail corrugation) has alway s been a critical issue in urban rail transit. In recent years, with the applica tion of a large number of vibration-damping rails in a metro line and the increa se of operation speed and load capacity of a metro vehicle, interaction force be tween a wheel and a rail is intensified, making rail corrugation more severe. Mo st of the damage to parts of the urban rail transit vehicle-rail system, such as fracture of elastic fastening and crack of the frame, are caused by severe rail corrugation. In addition, the severe rail corrugation can also bring strong vib ration and noise, affecting the lives of residents along the line and the ride c omfort of drivers and conductors. The most effective way to avoid or mitigate th ese problems is rail grinding. Currently, most metro operating units carry out p lanned maintenance on rail grinding according to specified operation time. Howev er, a development law of rail corrugation is complex and closely related to a ra il type and a train operation state, and the planned maintenance is often incons istent with the development law of rail corrugation, resulting in the waste of o peration and maintenance costs due to excessive grinding or frequent failures du e to insufficient grinding. State maintenance is a maintenance plan based on a r eal-time train-rail operation state, which can avoid the increase of operation a nd maintenance costs and frequent faults to the greatest extent. Therefore, a qu ick diagnosis needs to be performed on rail corrugation in real time.
