Test Your Knowledge: Steam Turbine Rotor Vibration

Steam turbine rotors are susceptible to bending during some operational evolutions, which can lead to excessive vibration and ultimately failure. Rotor bending that results in premature failure of steam turbine blades and other internal components is one of the most serious problems experienced in power plants. The problems often reduce plant availability by limiting generation and increase plant operation and maintenance costs.

Bearings and supports are designed to keep static and dynamic forces under control. However, under certain conditions, bending can occur. When it does, it can result in contact between stationary and rotating parts, often leading to cascading effects. Operators must understand certain phenomena, identify root causes of failures, and implement solutions to prevent future catastrophes.

Rotor bending can be caused by a variety of static and dynamic factors. This quiz is designed to test your knowledge of steam turbine rotor vibration failure mechanisms.
