The goal of this study is to develop a vibration-based electromagnetic energy harvesting prototype that provides power rail-side monitoring equipment and sensors by collecting wheel-rail vibration when the train travels. This technology helps rail–side in off-grid remote areas. article introduces principle, modeling, experimental test system, including (1) an with DC-DC boost converter lithium battery charge management function, (2) wireless sensor nodes integrated accelerometer...
To analyze the reasons for rail clip fracture, characteristics of corrugation were first measured using a meter. The vibration acceleration fastener clips at sections with/without was measured, and effects on analyzed. After this, vehicle--track coupling dynamic model refined system established in order to study stress critical points. Finally, grinding limits determined based fatigue analysis method damage accumulation theory from aspect life clip. results showed that main wavelength...
This article presents a prototype of wireless rechargeable sensor nodes for the health monitoring urban rail corrugation. The proposed system includes local energy generator constructed based on electromagnetic-induction principle, DC–DC booster converter, nodes, and an analysis interface using Littlewood–Paley wavelet transform methods. A vehicle–track interaction model is established that considers corrugation as irregularity excitation source to predict dynamic response railway tracks...
This paper is concerned with an experimental study of improved slotted stand-off layer rail dampers in reducing railway vibration and noise. To achieve the goal, based on idea molecular design, polyurethane/vinyl ester resin interpenetrating polymer network damping materials high properties was developed laboratory for material layer. The effects vinyl organic small molecule hybridization were investigated. structural style damper ease installation removal situ. Then, these improvements used...
Abstract The condensation reactions of formylferrocene with active methylene‐ containing compounds were achieved by microwave irradiation, grinding or heating in water, moderate to good yields. structures confirmed 1H NMR, 13C IR spectra, and elemental analyses.
This paper presents the solution on soft soil layer’s collapse of Xin Kailing Tunnel in China based analysis its causes. The effect is evaluated by site survey and finite element analysis. results show that geological factor mainly leads to collapse; crucial preventing from happening give a better description tunnel face, analyze predict conditions wall rocks which are front face time evaluate precisely whether supporting system strong enough or not; effective ways solve problem strengthen...
To improve the accuracy of vibration velocity monitoring during blasting in soil layers, this paper provides a method and device for data correction by combining finite element software actual engineering test data. Based on length pedestal exposed to surface geotechnical body, structural model corresponding each is established. Moreover, predetermined external excitation load applied outside function obtained analysis stress The solves problem low measurement establishes results show...
