Analysis of Ground Vibration near a Railroad
The 9th International Symposium on Recent Advances in Exploration Geophysics (RAEG 2005), 2005 The ground vibration generated by the Shinkansen, Japanese super express train，can be problematic for people and structures nearby. The purpose of this study is to make clear the mechanism of the ground vibration generated by a train and to develop a numerical simulation tool which can quantitatively evaluate the effect of wave filtering. This study is

Vibration diagnostics of transportation structures on railroads
Vibroengineering ProcediaThe article presents the results of the natural frequencies of vibrations of the span structure during the express-diagnostics, to excite the process of vibrations of the structure the pulse impact of the concentrated load of small mass is applied in the middle of the span structure (the method of small pulse impacts – “human jump”).

Vibration Analysis of Railroad Vehicle by Evaluating the Coupled Passenger-Carbody Vibration
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 2006 Although the weight of passengers can be considered as an increment of carbody mass itself in design of train carbodies, it has been shown that the passengers mass does not behave as a mere increase in mass because of the existing coupled vibration between passengers and carbody.

Analysis of Vibration Energy Harvesting from Power Consuming Devices
, 2020 : Vibration energy harvesting is one of the most promising technologies. The majority of current researchers obtain 10 mW to 100 mW power,[2] which has only limited applications in self-powered wireless sensors and lowpower electronics. The vibrations in
