  Critical Speed Analysis

The Project Manager undamped critical speed analysis reveals the basic behaviour of the rotor-bearing system in dynamic equilibrium in absence of damping. Pedestal effect also can be incorporated.

The Project Manager intersection of the rotor lines and the bearing lines should be away from the operating speed range in order to avoid resonances. In the event this is not the case, then the analyst have to find the way to get it. Usually, the easiest way is to change the operating speed. Bearing modification follows.

This is the second mode shape of a rotor. Mode shapes are used for field balancing purposes.
