Analytical techniques

Testing methods, such as the so-called Finite Element Method (FEM analysis) use a 3D model designed with a computer program to provide information on physical values, such as static and dynamic linear and non-linear voltage ratios, natural frequency, bolt strength and weld seam strength.

Comprehensive calculations about structure mechanics, electromagnetic and thermal properties can be made prior to manufacturing based on the three-dimensional finite-element methods (3D FEM) and using various simulation tools.REO engineers and technicians work with the software SOLIDWORKS or when calculating the bolt strength with MDESIGN.

3D FEM magnetic-field calculations


The method enables detailed calculations about the magnetic flux densities and energies, extant of leakage fields, inductances and much more. This data gives information about the influence on neighbouring equipment and leads to compliance with the required standards. Optimisation procedures get right to the heart of the manufacturing process a REO to ensure production is consistently efficient.


Calculating the bolt strength

When calculating, the resulting static forces can be analysed according to the static and dynamic load cases using the finite element model.
The calculation according to VDI2230 is then made using the program MDESIGN.


3D thermal simulation

Further testing and simulation, such as 3D thermal simulation, add to the set of analysis tool available to REO and provide insight into quality and potential for improvement of the components. Used in addition to three-dimensional electromagnetic field calculations, it is a further important analysis tool because it enables us to see inside the material and gain important information about local hot spots that can, over time, influence the expected service life. On top of that, complete thermal sequences can be simulated, giving information about thermal behaviour and help in making decisions about the required cooling system depending on the operating conditions.
