A Campbell diagram plots the system's natural frequencies against its rotational speed. Critical speeds occur where the "order lines" (multiples of running speed) intersect these frequency curves. Whirling Modes: These are dominant deformation patterns that split into (rotating with the rotor) and (rotating against it) modes due to gyroscopic effects. Stability Analysis: This identifies self-excited vibrations like : 150 MW steam turbine driving a hydrogen-cooled generator

: Research by experts like Dara Childs highlighted that components previously thought to be "secondary," such as annular seals, actually provide massive amounts of stiffness and damping that can make or break a machine's stability . A Campbell diagram plots the system's natural frequencies

For those seeking deeper technical proofs, mathematical derivations, and expanded data sets, searching for will yield several industry-standard papers from the Texas A&M Turbomachinery Symposium , which remains the gold standard for peer-reviewed rotordynamic literature.
