The mitigation of vibrations accompanying the running urban rail transport must be done effectively using the patented Vibration Energy Harvesting Dampers designed to provide dual results: reduction of harsh vibrations and producing the additional electrical power. The proposed technology is the implementation of Vibration Energy Harvesters combined with re-tuning mass damper. The device could be successfully introduced in rail supports (crossties), vehicle bogies and other vibrating components of urban rail transport. The approximate estimates for crossties show that the installations of vibration energy harvesters allows get around 25 kW per one running Toronto TTC Subway train, Paris Metro train or 20 kW per one running Calgary C-train. It is necessary to highlight that these kilowatts now are known as lost energy and never used. The analysis of dynamical performance of patented devices is presented in application to components of the vehicle bogies and rail supports. The experiments illustrate the compliance with theoretical predictions and efficiency of proposed Vibration Energy Harvester Damper operating mainly in low frequency interval.
