A Review on the Current Methods of Railway Induced Vibration Attenuations

Abstract

Railway ground borne vibration is a major problem for high-speed and intercity trains. This problem causes many environmental as well as financial problems for railway companies. In the past decades, there have been numerous methods and strategies to avoid the excessive vibration from vehicles. Many of these methods have been tested and used in tracks and surrounding structures while others are still theories. This paper intends to discuss the current practice in railway vibration reduction and the effectiveness of each method for the different track, vehicle and structures. The methods are divided into three groups; in track, in the path and at the destination solutions. For each category, the results from state-of-the-art research and practice have been presented and conclusion on the appropriate methods and strategies for each case has been made.

Noise Control of the Beginning and Development Dynamics of Faults in the Running Gear of the Rolling Stock

“…It is known that the running gear of a rolling stock breaks down due to the initiation of various defects, such as wear, crack, fatigue deformation, etc. [1][2][3][4][5]8]. In some cases, they lead to disastrous consequences.…”

“…Receiving the information on deviations from the nominal readings of the controlled parameters (temperature, vibration, noise, etc.) during movement, the driver of a high-speed passenger train informs the dispatcher, who, in turn, informs the relevant units [1][2][3][4][5].…”

Control of the Beginning of Accidents in Railroad Operation Safety Systems in Seismically Active Regions Using the Noise Technology

“…It is known that a prerequisite for achieving high competitive ability in the transportation market is the compliance of rail transport with the growing demands for speed, safety and comfort. The significant advantages of this mode of transport in comparison with other types offer great prospects in increasing the volume of traffic and at the same time require the improvement of this mode of transport [2][3][4][5][6][7][8][9][10]. There are great achievements in this area at present.…”

“…However, the seismic activity in some regions can create problems. The most important and vulnerable elements of rail transport are the moving part of cars and railroad tracks, the insufficient monitoring of the condition of which does not ensure the proper safety of the rolling stock [1][2][3][4][5][6][7][8][9][10]. As the railroad passes through seismically active regions, additional requirements for traffic safety appear.…”

“…For this purpose, extensive railroad communications with modern bridges, tunnels and stations have been built. This complex infrastructure is managed by many different modern monitoring and diagnostic systems [1][2][3][4][5][6][7][8][9][10]. These systems ensure a high level of efficiency and safety of rail transport.…”
