Discrete Element Method Simulation of Railway Ballast Compactness During Tamping Process
Railway ballast tamping operation is employed in order to restore the geometry of railway track distorted by train traffics. In this paper, based on analysis of tamping principle, the discrete element analysis model of railway ballast is created using the discrete element method, numerical simulations are performed to study the change of railway ballast compactness during tamping process. This ...
متن کاملDiscrete Element Modeling of Dynamic Compaction with Different Tamping Condition
Dynamic Compaction (DC) is a common deep compaction method that is usually used for densification of coarse-grained soils. Although traditional continuum-based models such as the Finite Element Method can be successfully applied for assessment of stress distributions or deformations induced by DC, they are typically not adequate for capturing the grain scale mechanisms of soil behavior under im...
متن کاملTamping Planning in Railway Maintenance
Optram is a computer software for evaluation of track geometry quality data, used as a decision support in planning and follow-up of tamping maintenance for Swedish railways. The software was introduced at the Swedish Transport Administration year 2009 but has not reached the intended number of users. The purpose with this thesis is to suggest how Optram can be improved as a decision support in...
متن کاملDiscrete Element Modeling of Railroad Ballast Settlement
This paper presents findings of a railroad ballast Discrete Element Modeling (DEM) research study focused on investigating ballast settlement under repeated wheel loading. In this approach, the ballast layer is modeled as an assembly of aggregate particles, AREMA No. 24 ballast gradation with different shapes and angularities and rough surface textures. The study matrix considered three differe...
متن کاملA Domain Decomposition method for granular dynamics using discrete elements and application to railway ballast
The paper is devoted to the development of a non overlapping Domain Decomposition method adapted to granular dynamics. The formulation and the efficiency of such a method are well established for structural mechanics. In order to extend this approach to granular systems a so-called primal splitting of the domain is chosen because it is a less intrusive method for software development. Once the ...
