Summary: This paper presents an approach based on cepstral analysis of axle-box accelerations for continuous wheel condition monitoring. The introduction of the navewumber domain allows for monitoring wheel wear and detecting possible defects based on peak amplitudes. The method is validated on synthetic and real data, providing robust features for on-board wheel condition monitoring and further advancing predictive maintenance of railway wheels.

Summary: Deep learning models can successfully recognize machine health conditions from vibration data. However, most studies have focused on lateral vibration data and ignored torsional vibration data, which could be advantageous for diagnosing gear faults. This study presents a large gear fault dataset and evaluates the performance of convolutional neural networks on both lateral and torsional vibration data.

Summary: By using a developed braking system torsional dynamics model, this study investigated the effects of dry and wet rail surface conditions on system dynamic responses. Furthermore, the system stability was explored under different disc-pad friction and wheel-rail adhesion characteristics, revealing the interaction mechanism between the disc-pad and wheel-rail sub-systems. The results showed that the wheel-disc torsional vibration was more complicated under wet rail surface conditions, and the braking system had worse stability when negative slope characteristics of disc-pad friction and wheel-rail adhesion were combined.

Summary: The study focuses on the detection of polygon wear of railway wheel (PWRW), a common wear fault in railway vehicles that can cause strong periodic excitation, decrease passenger comfort, and impact operational reliability and safety. A detection framework based on the angle domain synchronous averaging technique (ADSAT) using vertical axle-box vibration acceleration (ABVA) is proposed to improve the accuracy of PWRW detection. Results show that the proposed method can achieve order detection that traditional methods cannot, while also reducing the influence of background noise.

Summary: This paper develops a methodology to determine a maintenance limit for rail corrugation from the perspective of vibration fatigue failure, using the axle box acceleration spectrum and the transfer function of the wheel-rail system. The newly developed maintenance limit is considered more reliable in suppressing the vibration fatigue failure of the bogie.

Summary: This article proposes a state and disturbance estimator (SDE) for bridge structures based on a moving point load train model and estimating the average train axle mass. The proposed SDE is systematically tested through simulations and shows good estimability. A linear quadratic regulator is designed and combined with the SDE to evaluate the closed-loop performance for damping the bridge vibrations during train crossing.

Summary: This study investigates the reduction of Primary Yaw Stiffness (PYS) in railway vehicles by integrating inertance into the primary lateral suspensions to improve track friendliness without sacrificing passenger comfort. Systematic optimizations identified several beneficial configurations that can reduce PYS by up to 47% compared to default vehicles, potentially saving 26% in Network Rail Variable Usage Charges, while maintaining RMS carbody lateral accelerations stable.
