COMSOL (Burlington, MA) announced updates to COMSOL Multiphysics® modeling and simulation software that include a Rotordynamics Module. The module is designed to help engineers analyze vibrations due to centrifugal forces and other gyroscopic effects in rotating machinery. The module helps confirm that rotor vibrations are contained within acceptable design limits by evaluating critical speed, whirl, and bearings. Users can post-process their results directly within the software and present their analysis results as Campbell diagrams, modal orbits, harmonic orbits, waterfall plots, and whirl plots.
