Operational Deflection Shapes ODS

Hey all!

I'd like to enhance the investigation of the resonances of a mechanical system model incluing flexibles structures. Is it possible to extract operational deflection shapes from the System after the simulation using the Adams PPT? Or should I stop the Simulation at a certain time step(system state) and do a linear mode analysis?

What are your thoughts on this?

Kind Regards

Thanks!

So if I get you right I'll try the following.

1. Set up the solver simulation script like you proposed

2. Run a scripted simulation

3. Run a normal mode analysis using the simulation control (by hand)

..I just want to get sure that I linearize the model for the time step after which the simulation script ended, and not in initial conditions. How can I actually double check this?

Kind Regards
