help!!!complete modal analysis,and now?

[luigi.paiano]

Hello everyone,
It bothers me to ask you the request you read but I'm right in the ball.
I performed the modal analysis of a manipulator and found some way of vibration for my thesis.
I would like to apply this result somehow but I have no idea how to do it.
I thought, for example, to set a certain trajectory of the arm and compare the ideal movements in the absence of vibration with the real ones. But there were two weeks left from the delivery of the thesis and I have no idea how to set such a problem.I also wonder: what could be the causes of vibration in an industrial manipulator? once identified you would need to model them to get an answer, how to do?
I use ansys.
If someone has material on the way, on their application I would be happy to have it.
thanks to all

vibrations on manipulators can be due to both the acceleration movement and the opening/closing of the clamp, the rotation of the squilibrated engines, the games of the cinematisms.. I think of everything that moves and which has inertia above all unbalanced.

with ansys I never cuffed on the ways of vibrating.

and what do you use for modal analysis?

I do everything with cosmos integrated in sw. It's like the fatigue analysis we did... you always have to build the woler turn by hand... or with excel as I do. nothing lives on its own. Unfortunately, there is always a part of hand calculation for all analyses, or it is necessary to verify and compare or to have data necessary for simulation.
