modal analysis
modal analysis
(OP)
Hi specialists :)
after I performed a modal analysis with 5 instances (respectively parts) and the first ten modes, I would like to know if it's just visually possible (via visualization) to understand which instance or which combinations of instances are responsible for which modes.
Summary:
Is there a way to get to know, which instances are responsible for which modes?

What's the difference between natural frequency and modes?
I think i didn't explain the question that good. I know how to visualize the seperate modes. My assembly has 5 instances. I guess every assemblymode has its own main-activator (1 out of these 5 instances). So with my visualisation its hard to understand which instances are responsible for that one mode. Because the construction-instances are very similar.
Is there another way apart from the visualisation to get to know which instances are the main-activator for each assembly-mode?

RE: modal analysis
You are performing modal analysis of the structure as a whole, there is no such thing as a "main-activator". The eigen solver does not "see" five instances, it just sees a single structure with stiffness and mass properties, nothing more, and solves the eigen problem for that single structure.
Each instance will probably have local modes where the other instances are doing very little, but that would happen inside a single instance model in local areas as well.
