Design of Advance Compacting Tool for Railway Track: A Review

Maintenance has long been an important part of rail roading. Under repeated loading from traffic the track progressively moves, causing deviations from the desired vertical and horizontal alignment. Compacting is the process to restore the geometry and rearrange the ballast under the sleeper to keep the track in position and provide it with a homogenous ballast bed. The track geometry should be measured regularly or at least the track should be compacted at regular intervals to ensure that trains are able to travel safely at the normal speed of line. This paper deals with the design modification of the compacting tool used in compacting machine to restore geometry and rearrange the ballast. In this project we will be creating CAD model of the existing compacting tool and determine the stresses and failures occurring in tool. After detailed study and analysis on existing tool we will modify and perform analysis for the improvement of the compacting tool for minimum stresses and failures. Thus comparing the results for the both modified and the existing tool, the tool with the minimum stresses will be taken into consideration.
