Thank you for the reply. Thing is i am using spring (with damping) in three direction to represent the damper. I also have structure damping of 0.02. I am using mode super position method to performe the harmonic analysis.
I have some question regards to that.
- which damping will be taken in to account in harmonic analysis ? (damping from spring or over all damping coeff.)
- do i need to use full analysis instead of mode super position ?
- which solver gives the better result for modal analysis ? full damped or reduced damp ?
Thank you in advance !!
