    Relating Random Vibration Cycles to Failure to Time

    Thanks guys. The example Stienberg uses is a pretty simple object and he just uses the natural frequency to relate the cycles to failure back to time. Its basically what I had followed but then gotten stuck at with trying to relate cycles to time in a system with more than one natural...

    Relating Random Vibration Cycles to Failure to Time

    Hi guys, I have a simulation I've run a random vibration analysis on for a mounting bracket for an automotive application. I've applied a PSD input to the model and obtained the equivalent stresses for three standard deviations. I've then taken the S-N chart for the martieral and used Miner's...
