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 for the reply!

Can I define a solver simulation script that

1. Runs a dynamic simulation to preload the system via constraints and external loads

2. Deactivates the forces and constraints

3. Linearize about the last configuration and calculate the normal modes

..?

I just looked up the the commands and I don't find the one for the normal mode Analysis. What does eigen solution calculation do? Can I investigate frequencies and mode shapes with it?

Kind Regards
