Electrical engineering does not only deal with dynamics and strength, but also with operability analyses. The most common structures are switchgear cabinets and electric motors in manifold versions with regard to constructive design and equipment as well as electric motors, generators, drive and control elements.
Stability proofs are normally realized by means of computational simulation with finite element models. Simple proofs of functionability via deformation parameters are also realized by calculations. In case of complex components we carry out experimental proofs of functionability by means of vibration tests.
Apart from regular operating loads we also deal with special loads of external events, for example earthquakes.
In normal operation, the switch cabinet protects the electrical or electronic components from external influences such as dust or water. In exceptional situations - for example, in the event of an earthquake - the entire system is exposed to extreme loads. However, everything depends on the fact that the control system of the plant continues to function even then. We therefore deal with the
- operability as well as
- isolation against shock and vibration
of switchgear cabinets with electrical components. We provide stability evidence via computational simulation by means of FE-models, which are generated on the basis of your CAD data. In case of existing problems, constructions can be optimized by means of simulations.
We also determine the operability of electrical components in vibration tests, e.g. on a hydropulse system or on uniaxial to three-axial shakers/shaking tables.
Here we work according to the following national and international standards, e.g.
- ASCE 7, ICC ES 156,
- KTA 2201.4,
- IEC, IEEE: IEC/IEEE 60980-344, IEEE 344, IEC 60980,
- USNRC and
Whether in the context of new constructions, conversions or retrofits: we support plant manufacturers and operators in the design of entire plants or individual components in all structural-mechanical issues. Due to our expertise built up over many years, we are particularly consulted for the following load cases:
