After many years of service, a cast roller support housing failed on a railway turntable. The locomotive manufacturer needed to replace it with a new roller-mounting bracket of fabricated construction.
The design of the new roller support was based on the following approach: A finite element analysis model (FEA model) was developed using Strand 7 software for the original unit to explore the stress levels experienced and to determine the critically stressed areas when a locomotive loads into the turntable.
Measurements were taken from the original failed unit, as drawings were not available. It is understood that the original unit failed because the roller shaft pin became loose, rather than it being of inadequate capacity.
