Random response analysis

A random response analysis:

  • is a linear perturbation procedure that gives the linearized dynamic response of a model to user-defined random excitation; and

  • uses the set of modes extracted in a previous eigenfrequency extraction step to calculate the power spectral densities of response variables (stresses, strains, displacements, etc.) and the corresponding root mean square (RMS) values of these same variables.
