Tamping 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 کاملInvestigation of the Influences of Track Superstructure Parameters on Ballasted Railway Track Design
The main design criteria of ballasted railway tracks include rail deflections, rail bending stresses, rail wheel contact stresses, sleeper bending moments and ballast sleeper contact pressures. Numerous criteria have been defined for the design of ballasted railway tracks owing to the various mechanical properties of track components and their complex interaction. Therefore, railway track desig...

متن کاملDiscrete 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 ...
