In the development of high-tech mechatronic products and systems, the need for a first-time-right solution is increasingly important. Essential for such a requirement is predictive modeling. Here, the system is modelled and simulated to gain insight into its performance up-front.

Traditionally, lumped-mass rigid-body modelling has been used for this purpose, but as 3D geometries become more complex, a shift is made to finite-element-modeling (FEM) analysis. FEM analysis is capable of handling complex systems, directly relates to the designed geometry and comes with intuitive visualization.

Sioux has developed tooling to extract a state-space representation from the FEM analysis and actively uses this method for the design of its systems, e.g. by performing time-simulations or frequency domain analysis in MATLAB. The next step is to interconnect multiple of these models, a process called substructuring. This enables, for example, to interconnect viscoelastic materials and predict their damping contribution.

However, due to the limited numer of Eigenmodes calculated, the inter-component compliance is not correctly represented. Superelement generation methods, such as the Craig-Bampton method, do allow for an exact match of the compliance of the systems while simultaneously providing a more accurate representation of standalone systems.


Develop, implement and test a compliance compensation method by superelement generation, such as Craig-Bampton, for a high-tech system and prove the accuracy of this method.


  • Make a FEM model of the system to be tested.
  • Apply traditional FEM analysis and state-space generation for a baseline analysis.
  • Study the theory behind different superelement generation methods and develop a method best suited for the application.
  • Test and verify the accuracy of this superelement based method.
  • Apply your method on an in-development high-tech system.
  • Use the developed method to combine multiple FEM models or add discrete damping.

  • Working on innovative technology
  • Challenging, dynamic and varied work
  • A comfortable and personal work environment
  • Plenty of opportunities for personal development
  • Great carreer opportunities
  • Contributing to a safe, healty and sustainable society
