Hi guys,
currently I'm simulating a simple cantilever. The first thing i did was to determine its eigenfrequency. I got a value of about 504.5 Hz.
I'm interested in the deflection of the beam as a function of the (excitation) frequency. So I atteched (as recommended in the forum) an Edge Load to the free end of the cantilever.
When I don't use a damping i get a pretty high deflection. Furthermore, when the resonance frequency of the cantiliver is equal to the excitation source the simulation quits with an error (The relative error (0.0012) is greater than the relative tolerance.).
For me it is logical that the simulation stops. Because an undamped system would have a too huge displacement.
But when i introduce a Rayligh damping (mass damping parameter = 2/s and stiffness = 0) my cantilever has his lagest damping at his resonance frequency.
Has anyone an idea how I can fix this???
