DyRoBeS™
DyRoBeS is a powerful and sophisticated software tool for rotor dynamics including comprehensive bearing analysis. The procedure is based on Finite Element Analysis (FEA) which allows for multishaft designs and modeling of bearing housings, and mix at continuous/discrete elements. The FEA technique also provides more accurate predictions of natural frequencies, forced response, and rotor stability. There are also three rotor dynamics modules which analyze lateral, torsional, and axial vibrations of multishaft and multibranch systems.
DyRoBeS provides the engineer with the tool to analyze a rotor/bearing system. The engineer can modify the design and investigate the sensitivity of the dynamics of the rotor geometry, unbalance, seal wear, bearing changes, and low frequency excitation.
The program contains extensive modeling, analysis, and pre- and post-processing capabilities. This Windows® based software is very user-friendly and easy to use. The operation is entirely consistent with the industry standard for the windows environment.
Lateral Vibration
The lateral vibration of the discretized system is described by two translational and two rotational coordinates at each finite element station. The motion of a flexible support is described by two translational displacements. The analysis for lateral vibration contains:
- Multishaft, multi-material capability
- Static deflection & bearing/constraint reactions
- Critical speed analysis
- Critical speed map analysis
- Whirl speed & stability analysis
- Steady-state synchronous response due to unbalanced shaft bow or disk skew
- Systems with linear bearings
- Systems with non-linear squeeze film dampers
- Time transient analysis
Torsional and Axial Vibrations
For torsional and axial vibrations, the motion of each finite element station is described by a rotational displacement for torsional vibration and a translational displacement for axial vibration. The analyses for the torsional and axial vibrations are:
- Undamped natural frequency calculation
- Steady-state forced response analysis
- Short circuit transient analysis
- Startup transient analysis
Bearing Capabilities The following predefined bearing options are provided in the program:
- Fluid film journal
- Tilting pad
- Ball and roller
- Pseudo-bearings
- Squeeze film damper
- Rolling elements with clearance
- User defined stiffness/damping matrix
- Temperature dependent lubricant properties
