Frequency Modes

Use modal frequency analysis to test a model for its natural resonant
frequencies (for example, a rattling muffler during idle conditions, or other
failures).
Each of these incidences may act on the natural frequency of the model,
which, in turn, may cause resonance and subsequent failure. The mode shape
is the displacement shape that the model adopts when it is excited at a
resonant frequency. Autodesk Inventor Simulation calculates the natural
frequencies of vibration and the corresponding mode shapes. It presents the
mode shapes as results that you can view and animate. Dynamic response
analysis is not offered at this time.
