    Hopefully the pulley isn't that unbalanced that it vibrates. If it does, replace the pulley. The bigger the pulley, the more vibration you might expect as the rotational speed increases. If the system is vibrating, I'd look for a damaged pulley first.

    Vibration is a result of rotational imbalance. It could be due to a bad bearing, a misshapen pulley. A damaged pulley or other factors. You cannot predict vibration without knowing the mass of the imbalance, rotational speed, harmonics etc. No formula exists to my knowledge. Sorry I can't help more.
