In recent years, condition monitoring technology has been actively developed aiming at more safer operation and maintenance cost reduction. In this study, condition monitoring device attached on trackside is used for the monitoring of railway bogies in terms of the diagonal wheel load imbalance ratio \(R_d\) . In general, the ratio \(R_d\) widely varies even though the same train pass on the trackside device. Therefore, the factors that cause the variation of \(R_d\) should be investigated to improve the measurement accuracy. In this paper, the correction method to reduce the variation of \(R_d\) is mentioned and is examined utilizing experimental data collected by roller-rig test stand. According to the analysis with collected data during service operation, it is confirmed that the proposed correction method is more effective than previous data processing method with trackside device in terms of estimating the value of diagonal wheel load imbalance ratio.

摘要

In recent years, condition monitoring technology has been actively developed aiming at more safer operation and maintenance cost reduction. In this study, condition monitoring device attached on trackside is used for the monitoring of railway bogies in terms of the diagonal wheel load imbalance ratio \(R_d\) . In general, the ratio \(R_d\) widely varies even though the same train pass on the trackside device. Therefore, the factors that cause the variation of \(R_d\) should be investigated to improve the measurement accuracy. In this paper, the correction method to reduce the variation of \(R_d\) is mentioned and is examined utilizing experimental data collected by roller-rig test stand. According to the analysis with collected data during service operation, it is confirmed that the proposed correction method is more effective than previous data processing method with trackside device in terms of estimating the value of diagonal wheel load imbalance ratio.
