FATIGUE DESIGN CRITERIA FOR CARBODY BOLSTERS

The purpose of the static test is to prove design and, more or less, verify stress calculations of the bolster. Where, this is a step in the right direction, it does not point out indeterminates and areas of concentrated high stresses. It is these high stress areas that will lead to fatigue failure of the bolster. Unless these areas are located and steps taken to correct these conditions, failure will continue to occur. In making these tests, employed was the use of photoelastic analysis, which has helped in pointing out high stress areas that calculations of the bolster would not indicate.
