Vibration analysis Help

Hi All,

I do an modal analysis for a constrained Bracket, i want to Know the value of the maximal displacement in the first mode,

i don't have any idea about the excitation that i shoud apply, Or the nature of vibration analysis to do

Any help please,

Hi Oggy

I do an modal analysis for a constrained Bracket, i want to Know the value of the maximal displacement in the first mode,

You can use measure panel get the maximum displacment. But why do you want to see the displacement for a modal analysis?

it is not an actual displacement but a resultant displacement.

Hi Prakash,

I don't see the displacement for a modal analysis because such analysis give us juste frequencies & eigen mode ,

My question is : what is the analysis that i shoud apply to have displacement of my bracket in the first mode ?

is it modal frequency response ?

if yes, wich excitation i shoud use ?

Hope my question is clear known

Thnaks,

No one for help ?

Hi Oggy,

I lost your question in flow. You can try frequency response analysis where you can see disp, stress, for a frequency range.
