DyRoBeS v20.20

Dyrobes is a complete rotordynamics software tool that is powerful and versatile, yet easy to learn. Developed for the working engineer, Dyrobes offers complete rotordynamic analysis, vibration analysis, bearing performance and balancing calculations based in Finite Element Analysis.

New Features and Improvements

Improvements for Ver 20.21

Released August 8, 2018, featuring:

• Add Element Torque Table for Torsional Short Circuit Transient Analysis requested by Solar Turbine
• Add more digits text output in the transient analysis requested by Curtiss-Wright
• Include the latest Hasp drivers from Gemalto

Improvements for Ver 20.20

Released April 25, 2018, featuring:

• Improve numerical integration stability for the Transient Analysis
• Add cut-off low frequency to eliminate the low frequency noise in the transient analysis due to initial conditions and constant loading
• Improve the BePerf – Tilting Pad Bearing Advanced Feature option
• Enhance some Postprocessor Graphics

Improvements for Ver 20.10

Released February 16, 2018, featuring:

• Add Analysis Type 13 – Morton Effect (optional program)
• Add Analysis Type 14 – Multiple Analyses for the same rotor file
• Enhance PostProcessor Graphics in the Time Transient Analysis – Frequency Domain

Improvements for Ver 20.00

Released December 2, 2017, featuring:

• Add Design Comparison in Rotor to compare different designs:
  1. Compare two different (.rot) files
  2. Same rot file, but different bearing files
  3. Same rot and bearing files, but different bearing variables
• Add Bearing Type 15 in Rotor. This option allows the Rotor and BePerf to be fully integrated, for linear analysis.
• Add new features in BePerf for fixed-lobe and tilting pad journal bearing design, including parametric study and design comparison tools.
• Add or modify more lubricants into the oil library.
• Transient Analysis in Frequency domain, the initial condition for the high speed point uses the final condition from the previous speed point.
• In the Transient Analysis, the integration time and time step are important for the FFT plot, therefore, add “Suggested Time Step” feature for the integration time and time step.
• Add velocity and acceleration in the FFT displays.
• Add damping factor vs. frequency ratio (API 610) in the Post Processor for the Whirl Speed and Stability Analysis.
