Failure analysis of railway freight car axle with finite method element

Abstract

Caring for goods transportation vehicles is a natural thing in maintaining conditions in order to stay in prime condition, especially in the most important parts. One of the sections of the most important in a vehicle carrying humans or goods i.e.as the wheel. Care extra is needed so that no occurrence of failure when used. The failure of a part when used can result in consequences are potentially disastrous to the possibility of man as the victim. Therefore, axle vehicles, especially rail are designed extremely reliable, with a maintenance inspection of a non-destructive manner periodically. However, in a situation unique, as the wheel to experience a state of tension complex as well as some of the conditions the voltage doubles, so that the failure of fatigue at the time used. Studies have clarified the equivalent stress, strain energy, as well as the safety factor of the cause of the fracture of the axle wagon railway transporter type of train railway that used to haul coal in which the analysis of the failure of the shaft fractures is done by simulation with the comparison material standards and materials that have been inspected by the journal related.
