    Ansys Workbench Harmonic analysis, full model vs mode superposition

    Hello, I am doing simulations to see how much a structure deforms when exciting with a acceleration amplitude on the full body, frequency range 0-200 Hz. Currently I am using a damping ratio of 1% in the in the mode superposition method. I also tried the full model but the result is very...

    Ansys Workbench Harmonic Analysis

    Hello, I am looking to simulate sinusoidal vibrations in the range 0-200 Hz for a structure. The method I am using is the full body acceleration in the harmonic analysis. However I have also tried it using base excition on the fixed support. The two method give similar but at some points quite...
