Description
Rail is a costly industry prone to punctuality having issues like catastrophic failure, largely due to lack of accurate information. Locomotives are the lifeline & strength of a country or a state, they run like RBC and WBC in our blood vessels transmitting contents.
Vibration analysis is one the best practice for mechanical maintenance of products in dynamic conditions which gives room for continuous real time monitoring using developed techniques and bifurcating methods to define the correct root cause of an early failure.
This case study helped to learn about the behaviour of rail asset’s wheels surface damages with respect to time. After a year of study on a prototype asset, it was concluded that vibration mapping technique can be used to identify the sub-surface damages on the locomotive wheel differentiating the stages of damage to asset with respect to time and can help predicting the faults/failures days in advance to stop catastrophic failures surprises. This case study can also help in calculating the reliability of a rail asset and taking a leap from Preventive maintenance to Predictive maintenance.
