Identification Method for Missing Cotter Pins in Catenary Systems Based on Stacked Denoising Autoencoder Network

Chengshi guidao jiaotong yanjiu
Objective When using convolutional neural networks (CNNs) for the state detection of catenary system cotter pins, the imbalance between positive and negative samples leads to a low detection rate of missing pins in the network model. Thus, a single-stage

Study on the mechanism of rolling contact fatigue in the central section of wheel treads for metro vehicles

机车电传动
Rolling contact fatigue (RCF) is a common form of wheel damage of metro vehicles, which has significant impacts on operational safety and maintenance of wheels. This paper focuses on the RCF observed in wheels used on a metro line in China.
