Moving people and goods requires energy and compliance with the current safety regulations. Based on our expertise in the aviation sector, we can apply our structural engineering knowledge to customer projects on the ground or in the water.

Over the years, we've been able to successfully develop, verify, and implement new designs of locomotives, monorails, roller coasters and ships. In the field of passenger transport, the safety requirements are increasing constantly. The proper application of lightweight construction and careful selection of appropriate materials (steel, aluminium, GFRP and CFRP, sandwich constructions, etc.) can help to reduce the energy requirements of vehicles in the future.

Vehicle design and structural verification

Our range of services includes concept development, design, and structural verification of any type of vehicle. Buses, trains, ships - you name it - we've got the structural aspects covered. Analyses of highly dynamic structures such as roller coasters and Ferris wheels are also part of our portfolio.

Our range of services covers:

Structural design

From the conceptual design stage all the way through to support during operation.

  • Feasibility studies
  • Design concepts for systems and components
  • 3D-CAD modelling
  • Production documentation
  • Lifecycle management

Aerodynamic and loads

The key to successful development in aerospace is correct loads.

  • CFD analysis and optimization
  • Load calculations based on CFD and analytical methods
  • Development of fatigue spectrums
  • Calculation of interface loads
  • Load definitions based on tests (wind tunnel tests, flight testing)

Structural calculation

Analytical analysis as a supplement to FEA is not just relevant in the concept phase. Certification authorities often require comparative calculations alongside the FEA. An analytical approach is also used sometimes for reasons of efficiency.

  • Structural strength verifications
  • Fatigue verifications
  • Buckling analysis
  • System analysis

Numeric calculations

Efficient application of CAE tools for economic product development.

  • Development of Finite Element Models (FE-Models) for static and dynamic analysis
  • Implicit analysis with NX Nastran
  • Linear and nonlinear structural analysis
  • Stability analysis
  • Dynamic analysis
  • Aeroelasticity
  • Thermal calculations (transient and stationary)
  • Topology and parameter optimization
  • Explicit analysis with LS-DYNA and NX Nastran Advanced Nonlinear
  • Impact analysis (buffer impact or crash)


We work in close cooperation with partner organizations to test material properties (structural strength, stiffness, flammability, toxicity), conduct crash tests, or assessing the initial start-up.

  • Development of test specifications and test plans
  • Selection of test organizations
  • Product testing
  • Documentation of test results


  • Development of certification plans
  • Certification documentation
  • Negotiations with certification authorities (e.g. TÜV)
