Vibrating mass, centrifugal force 175kN
Vibrating mass, centrifugal force 175kN
(OP)
Hello.
Below description:
We have unbalanced mass (M) about 50kg which rotates with frequency 50Hz. Vibrating mass produces centrifugal force equal 175kN. Vibrating shaft is connected to the rigid frame by means of rubber vibroisolators. Schema ilustates the case. Rigid frame is not fixed to the ground.


We are afraid that so big centrifugal force can fall over construction.
Below questions:
How should we shape rigid frame to ensure stability of the construction?
Is there any equotation which will show how big force would overcome this centrifugal force(175kN, 50Hz)? We are wondering what should be weight of rigid frame.
Best regards
Artur

It is certainly possible to work out what you ask, but it is not trivial either. I suggest you look at Thomson's Theory of Vibration book, or equivalent.

It is not clear to me how the vibration isolators are mounted. Is it possible that they will provide more displacement of the mass, resulting in more force?

Being an analysis of that.
