"Design better and faster" is the concept driving most new developments and ideas in today's high speed rotating machines sector. Enhancing products and processes is a challenge faced every day in this industry.
SAMCEF For Rotors, or S4R, is the cutting edge product you need to design your rotating structure and make sure the vibration level and loads transmitted to bearings and stators is kept under control.
SAMCEF For Rotors enables you to build your virtual mock-up according to your needs:
- 1D models for fast computations, even if model building and validation can take a bit of time
- 3D models for very easy modelling and/or non axisymmetric structures, but with higher computation times
- 2D multi-harmonics models that combine the advantages of 1D (short CPU time) and 3D (easy modelling)
3D structures can also be modelled from angular sectors if they feature cyclic symmetry properties. This method can even be extended for multi stages structures with different angular sizes for the sectors representing each stage.
Different model types can be mixed in the same global model to really insure that your model is as accurate and as efficient as possible and that you will obtain the best possible results in the shortest time. Several rotors with different orientations in space and rotation speeds can be modelled as wellas as non rotating parts, making S4R the best suited package to simulate devices as various as aeroengines, gas and steam turbines, turbochargers, centrifuge...
All these models obviously include specific features like gyroscopic effects, centrifugal stiffening... and are used in various computation types like critical speeds analysis and response to harmonic forces in both the frequency and time domains.
When studying the dynamic behaviour of rotating structures, a specific attention must be paid to the way they interact between themselves or with the ground. That is why S4R features a large library of bearings, squeeze film dampers and seals, as well as gear elements to potentially model gearboxes, reductor stages and take their own inertias and flexibilities into account in the global picture.
S4R being a professional solution, it comes with a state of the art GUI SAMCEF Field that is a generic Finite Elements Analysis interface that has been customized for the specificity of Rotor Dynamics computation. So it combines the power of a generic modelling tool with the ease of use of a dedicated interface that features data assignation on CAD geometries, automatic meshing or specific tools for post processing, like Campbell diagrams and automatic computation of critical speeds, frequency and/or time plots, mode shapes representation for different rotation speeds...
All these features take advantage of SAMTECH's 20 years of experience in the field of Rotor Dynamics and the interaction with several major players in the corresponding industries all over the World. |
