Hello,
I have some data of accelerations in the frequency domain, I wish to get displacements explicitly from the accelerations, the problem is that I don't know exactly what should I use, I've thought of some useful methods like double integrating the acceleration or dividing the acceleration by omega^2 since the excitation is harmonic, or get the accelerations in the time domain using Fourier transform in order to get displacements also in the time domain and not in the frequency domain and then double integrate the acceleration.
Can anyone guide me to the perfect method?
