Energy Harvesting from Train Vibrations
An investigation is carried out into how much energy can be harvested from the vibration of a passing train using a mechanical oscillator. The harvested energy could be used, for example, to charge sensors mounted on the railway track for structural health monitoring. The dominant frequencies due to a passing train are determined for a specific train and speed from a recorded acceleration time-...
متن کاملEquidistant Spectral Lines in Train Vibrations
We analyze in detail the seismic vibrations generated by trains, measured at distance from the track with high sensitivity broadband sensors installed for the AlpArray project. The geometrical restrictions of the network resulted in a number of instruments deployed in the vicinity of railway lines. On seismic stations within 1.5 km of a railway, we observe characteristic seismic signals that we...
متن کاملImpedance Modeling for Prediction of Train Induced Floor Vibrations
Laboratory and manufacturing facilities are frequently located in areas that experience high-frequency (greater than 30 Hz) environmental vibration. Such vibrations are a concern for the proper functioning of sensitive laboratory devices, precision manufacturing equipment as well as human comfort. A simple method to accurately predict the magnitude of high-frequency floor vibrations would allow...
متن کاملPerformance of Shred Tire Mixed with Railway Subgrade in Reduction of Train Induced Vibrations
In this study, the performance of shred tire mixed with railway subgrade is evaluated to reduce environmental vibrations caused by trains’ passage. Since incorporating the Shred Tire seeds in soil affects on its shear strength and deformability parameters so, the first stage of the study was allocated to conducting a series of laboratory tests such as the unconfined compression test, and CBR an...
متن کاملAn Impedance Model Approach to Predicting Train-Induced Vibrations in Buildings
In major cities around the world, urbanization and rising land prices have been driving an increase in real estate development adjacent to, and above in many cases, railway lines and other transportation corridors. Structure-borne sound and vibrations from traffic can be are annoying to human occupants; if high, they can also be disruptive to operation of manufacturing facilities, medical facil...
