MODAL ANALYSIS

MODAL ANALYSIS

MODAL ANALYSIS

(OP)
Hello

Do you know if it's possible to do a modal analysis in I-deas? (about frequencies and vibrations)

Best regards

RE: MODAL ANALYSIS

Yes.. it is possible..

Hello karhick11

Thank you for your answer. Do you have an idea of how I should proceed?

Thank you

 

RE: MODAL ANALYSIS

you can do modal analysis in I-deas, in a module called simulation. There are many steps you have to do like meshing, applying boundary conditions, creating solution sets and finally solving and viewing the results..

RE: MODAL ANALYSIS

(OP)
Hello,

Thank you for your answer. What I am looking for is the following:

To measure the vibration of a component with an accelerometer, then to take the data obtained, implement it in I-deas and calculate the modes of vibration (Fouriers Transform)

I know I can model the 3D and from there to do the vibrations calculation. But I want to do it the other way around: To measure the vibrations and to do the post-processing in I-deas. Do you know if it is possible? How can I import the data?

Best regards  

RE: MODAL ANALYSIS

yes.. you can measure the vibrations in accelerometer and you can import that data in I-deas as spread sheet format and you can apply those vibrations in FE model.
Better go for some detailed online tutorials.
