use, engineering design/analysis software tools authored by Wen Jeng
Chen, Ph.D., P.E., for complete rotordynamic analysis and
comprehensive bearing performance calculations.
The Finite Element based codes combine a user interface intuitive
enough for the occasional user, with a powerful set of modeling and
analysis capabilities for the most demanding requirements.
Extensive built-in modeling, analysis, post-processing and
visualization tools allow the user to work within a single integrated
environment. To aid the
user, the programs include context sensitive help, a standard Windows
help system, and an extensive set of examples. DyRoBeS-Rotor is the Rotor dynamics component.
Developed with the basic philosophy of providing powerful, but
easy to use tools for the working engineer, DyRoBeS-Rotor,
is capable of linear and non-linear analyses of free and forced
vibrations (lateral, torsional, and axial) as well as static deflections
of multi-shaft and multi-branch flexible rotor-bearing-support systems.
More than ten different types of bearings, dampers, and seals are
built in. In additional, a
number of analysis and design tools, including aerodynamic
cross-coupling calculations, rolling element deflection and stiffness
estimation, liquid annular seal analysis, calculation of inertia
properties of a solid, equivalent impedance of a bearing-support system,
rotor orbit analysis, and balancing calculations are provided. DyRoBeS-BePerf complements DyRoBeS-Rotor by
calculating Bearing steady state and dynamic Performance.
The wide range of bearing configurations which can be analyzed
include plain cylindrical, partial arc, elliptical, lobed, multi-pocket,
pressure dam, general fixed profile lobed, flexural/tilting pad with or
without flexible pivots, floating ring bushings, gas lubricated
bearings, and thrust bearings. The
solution includes automatic calculation of effective film temperatures
at operating conditions. In
addition to bearing analysis, the program also performs lubricant
properties analysis and oil flow calculations.
The bearing dynamic coefficients calculated by using DyRoBeS-BePerf
can be easily integrated into a DyRoBeS-Rotor model. Under
continuous development since 1991, DyRoBeS has
been rigorously validated and extensively tested by many academic
researchers and industrial engineers.
It is widely used by government agencies, universities, and
various industries around the world.
