Wiki Campbell Diagram. V rotorové dynamice analytický campbellův diagram pro jednoduchý rotor. Both plots are relevant.
A campbell diagram represents the vibration frequencies of a system at various operating rpms. The python script i mentioned in my previous post will plot the campbell diagram as function of ws or rpm based on the command line argument. The campbell diagram can be generated from machine design.
The campbell diagram is an overall or birds eye view of regional vibration excitation that can occur on an operating system.
½ or 1 predict shaft torque response to transients numerical integration time marching machine train start up with synchronous. In rotordynamics in rotordynamical systems the eigenfrequencies often depend on the rotation rates due to the induced gyroscopic effects or variable hydrodynamic conditions in fluid bearings etc. The rpm plot will not show whats happening above rated since the rpm is constant. Both plots are relevant.
