Structural mechanics

Precision design allowing for manufacturing tolerances and temperature variations: structural mechanics decides if it is hit or miss.

In ultra-high-speed shafts, structural mechanics design and optimization are key. This includes allowing for manufacturing tolerances, temperature ranges and material parameter deviations in the design. Depending on the material, Celeroton works with different stress hypotheses and safety margins on the strength values and, depending on geometric complexity, with analytical tools or Finite-element-method (FEM) to calculate the mechanical stresses. Integration in the system design is essential due to the many dependencies on all other technology areas such as thermal design or rotor dynamics.

Highest level of tightness, lowest leakage rates of turbocompressors with gas bearings in noble gas processing

Compressor applications frequently require a high demand for tightness performance of the turbo compressor. For many reasons this feature is important to minimize and avoid risks of health, environment, fire, failure and cost. Since 100% system tightness – even using O-rings is unfeasible, the method to achieve the required minimal system tightness level is crucial.

Application examples of the magnetic bearing CM-AMB-400 motor for optical applications

High speed rotating elements, such as disc shaped rotors crossing a beam, infrared and X-ray choppers, are used to deflect a beam. The modular assembly of the magnetic bearing motor CM-AMB-400 allows the use of an application specific rotor. The concept of the magnetic bearing motor is such that a beam can be guided in radial or axial direction to the rotor to be deflected or chopped by the rotation.
