What is Random Vibration Fatigue? Structures or Mechanical components are subjected to random form of loading. Wind Loads, Wave Loads, Car engine operating on different moving roads are such examples. Random loading changes over time. Random vibration involves dynamic loading conditions. Random Vibration Fatigue Three methods to compute the expected damage ratio due to random loading Fatigue.   Narrow Band Method   Steinberg Method   Wirsching Method Loading and response are random processes Frequency based fatigue is required for such loading conditions. They use statistical measures for solutions. Requires a Dynamic random vibration study run for Fatigue calculation. New Fatigue study involves stress PSD(Power Spectral Density) What are Dynamic Loads ? Dynamic loads are classified to deterministic or non deterministic. Deterministic loads defined are functions of time and predicted precisely. They are harmonic, periodic o...
