Visco-damper database characteristics

Beitrag von claudio_mend » Mi 28. Mär 2018, 15:25

Good afternoon,
I'm trying to use the viscous dampers that are available in the Rohr2 database, but am facing some difficulties apparently because the excitation frequencies of the input loads I'm using are high ( up to 114Hz).

I'm coming to results that are not damped as expected when using these devices. One of the hypotheses we consider to be causing this problem would be the possibility of the database containing information for a frequency lower than those prevailing in our model.

Is it possible to enter characteristic values for the dampers exposed to higher frequencies?

Thank you very much for the attention.
