ROTOR-E allows EDI to visualize and understand the complex vibrations of rotating machinery. With Rotor-E, we can identify your problems and develop solutions.
This software especially designed by EDI developers gives us the power to:
- display the critical speed maps, unbalance response plots, orbits, logarithmic decrement versus aerodynamic load plots, as well as 3D animate mode shapes
- obtain a direct eigenvalue solution for critical speed and stability calculations, solving for all roots
- utilize a sparse matrix solution for unbalance response, efficiently calculating the response at all stations
- predict vibration at every modeled point of the rotor over the entire speed range
- thoroughly analyze the lateral response of the rotor to ensure maximum reliability
ROTOR-E Analysis Capabilities:
- Performs all API lateral rotordynamic calculations including coupled train analyses.
- Allows bearings, seals, or aerodynamic loads to be located at any point.
- Presents the results of critical speed, unbalance response, and stability analyses simultaneously in plots and tables on screen.
- Accepts twelve parameters for modeling bearings and seals (four stiffness, four damping, and four mass terms).
- Generates damped or undamped critical speed maps.
- Models effects of pedestal stiffness, damping, and mass.
- Calculates vibration response due to unbalance at multiple locations Includes or excludes gyroscopic effects.
- Converts input and output to either English or metric units
