Combination of independent vibrations for fatigue analysis
Combination of independent vibrations for fatigue analysis
(OP)
I am working on the fatigue analysis of a component subjected to combined transportation and machine operating vibrations. I have time signals of fatigue stresses induced by transportation vibration and by machnie operating vibration seperately; but not both simultaneously. Both vibrations are indepnedet to each other. I want to know how to construct a time signal of fatigue stress under both vibrations simultaneously from the time signals I have, because it is difficult to measure it.
Thank you very much. Jian Chen

CombinedTimeHistory(t)=transportation(t)+machine(t)
