SAMCEF Rotor
SAMCEF Rotor is a general Finite
Element solution specifically adapted
to rotating machine analysis.
Rotor Dynamics Analysis
SAMTECH, Integrating CAE towards Professional Solutions
ABOUT SAMTECH
Founded in 1986 from the Aerospace Laboratory of University of Liège to allow
the development and commercialisation of the general purpose Finite Element
Analysis package SAMCEF, SAMTECH is now the leading European Company for
the development of Integrated CAE Solutions. SAMTECH provides its expertise to
industries like SNECMA, AIRBUS, EADS, ALENIA, ESA, SONACA, ABB, PSA, …
willing to increase their competitiveness by decreasing design time and costs and
optimizing their methodologies. In order to answer this objective, SAMTECH has
structured its competences around two main complementary activities:
- The “Software edition” activity which includes the development of
scientific software tools like the general FEA package SAMCEF, EUROPLEXUS
for explicit analysis or the open object oriented optimization platform BOSS
quattro.
- The “Engineering services” activity which provides customized solutions
such as consultancy, intellectual services and on-the-road projects. It includes
also assistance to prime contractors and high-tech subcontracts to
engineering offices, which belongs to industries, as well.
3-D MODEL
Rotors can also be modeled by
3-D shell or volume finite
elements. This model allows
describing rotors with complex
shape like impellers or fan. It is
possible to mix the 3-D model with the
beam model.
SAMCEF Rotor is a solution specifically
adapted to the dynamic analysis of structure
containing rotating components. It is finite
element based and allows to compute critical
speeds, stability, harmonic and time-transient
response of mechanical systems made of
rotating parts, fixed parts and linking devices.
ANALYSIS TYPES
CRITICAL SPEEDS COMPUTATION
Several methods are available and they can be used to solve bending, axial, torsional or coupled problems.
With the sweeping method, the user defines ranges of rotational frequencies whithin which complex eigenvalues have to be
computed.
The direct method allows directly obtaining the critical speeds as eigensolutions. It is used for undamped systems with
constant stiffness.
PICTURE AT A GIVEN TIME OR FREQUENCY
• It is possible to recombine the complex modes for a given phase
angle and to superimpose them on the initial structure.
Displacements, rotations and energies can be obtained;
• Complex displacements, rotations, forces, moments and
stresses after the harmonic response for a given frequency;
• Real displacements, rotations, forces, moments and
stresses after the transient response and for a
given time;
• For both frequency and time response,
it is possible to animate the result.
