Components operating in a mechanical vibratory environment are highly susceptible to fatigue damage phenomenon. The durability of these components is usually validated on shaker rigs, using an accelerated simplified test given by standards or derived from mission profiling and test synthesis process. Numerical simulation in the frequency domain, thanks to spectral models, can help optimizing this process, allowing verification and design optimization of components soon in the development stage.
