Overview of vibroacoustic isolators used in railway tracks

MATEC Web of Conferences, 2018
The paper presents an overview of vibroacoustic isolators used in railway tracks to reduce negative effects from railway traffic. These include single components or their assemblies, with different material characteristics and location in the track ...

Hybrid DEM-FDM Modelling of Ballasted Railway Track Performance

Infrastructures
The performance of ballasted railway tracks under cyclic loading is a critical issue in urban railway systems, where high traffic frequency and geometric constraints accelerate track degradation, leading to the accumulation of plastic deformations that ...

Geotechnical Properties of Ballast and the Role of Geosynthetics [PDF]

, 2006
The ballast and its engineering behaviour have a key role in governing the stability and performance of railway tracks. The deformation and degradation behaviour of ballast under static and dynamic loads was studied based on large-scale triaxial testing.

Numerical Analysis of the Dynamic Behavior of the Ballasted Railway Track Under Loading of Trains at Variable Speeds to Improve the Prediction of Dynamic Amplification Factors and Damage to Its Components

Shock and Vibration
This study contributes to the dynamic amplification effects of different speeds of trains on the behavior of the ballasted railway. The damage mechanisms of the main components of ballasted railway tracks were investigated in 3D numerical modeling using ...

ROLLING NOISE SIMULATION OF A RAILWAY VEHICLE [PDF]

, 2013
Rolling noise of the railway vehicles is occurred by the wheel/rail vibration excited bythe rolling surfaces roughness. This paper presents an acoustic model able to predict the rollingnoise level of a railway vehicle.
