Failure analysis for the bogie braking beam in working part of a tamping wagon
The failure problem of brakes in the bogie of the working part on a tamper wagon is brought out in this paper.Braking process under its working condition is simulated and the comparison is done between the motion simulation and the working principle of brake system.FEM analysis by ABAQUS is done to analyze the front braking beam which is suffering bigger force.Stress distribution from the FEM analysis is discussed to explain the failure places happen in reality.In the end,an arbitrary crack is assumed and the fatigue life of beam is work out to give a prediction of failure.
