Hello Guys,
i've vibration problem previously posted on forum but no progress made.
I think to have little bit more chance to understand the problem is to understand EXACTLY how orbit made in case of more than one components.
The orbit posted here coming from both 1X and 2X vector movement.
the first (8 shape) i made from 1X and 2X aprox at same amplitude
The second is made with the same vector but with 1X higher than before.

I don't want the interpretation of mechanical problem but only understand if my considerations are correct.

Furthermore i can investigate deeper to solve the problem.
