get price## Analyzing Critical Speeds with the Rotor Bearing

2017-5-25 A critical speed is the angular speed of a rotor that matches one of its natural frequencies. Finding the natural frequencies of a stationary rotor, however, is not enough to determine the critical speed. The real challenge comes from the fact that the natural frequency of the rotor depends on the rotor angular speed.

2018-5-14 Usually the critical speeds are desired to be 10% to 20% above or below the operating speed range. However, there are many rotors that operate on top of the second critical speed due to sufficient bearing damping. Often attempts to elevate the 2nct critical speed by increased bearing stiffness leads to serious 1st mode stability problems.
