Good morning to all,
I am new in the forum and I need some clarification on the use of ansys w. I am making simulations on a set that represents a laboratory machine subject to a harmonic force, which is why, I chose to face a harmonic analysis. in "analysis settings" under "damping controls", there is a voice, which takes the name of "constant damping ratio": reading about ansys' help, it is written that it is the easiest way to assign damping. My question is: is this depreciation value referred to the whole structure as an equivalent term of more damping to be understood as those due to the presence of other elements? on the internet I read that for steel structures the depreciation ratio (generally indicated with "zita"), is usually assumed constant and equal to 5% (immagin for the entire structure). so, can I directly set in that box 0.05?
thank you all, I wait for an answer.
p.s. the machine is used at room temperature. do you have a manual of nx 7.5 (possibly in Italian, if it exists)?
