Structure Engineering
Core competence demonstrated in more than 500 projects.
SPS uses the finite element method (FEM) to describe the behaviour of a structure from the early conceptual phase to final dimensioning in addition to analytical methods. Many years of experience with the finite element method (FEM) range from linear static analyses to complex dynamic analyses. Our standard tools are listed below. Other in-house tools maximize efficiency and minimize effort, e.g. for temperature mapping.
Our expertise includes
01
Modelling
Simulation models based on CAD data with problem-adapted discretisation.
02
Mechanical analyses
- Statics (linear and nonlinear)
- Dynamics (modal analysis & vibration, including sine-, random- & micro-vibration)
- Strength verifications
- Deformation analyses (including moisture- and gravity release simulation)
- Stability analyses (imperfection modeling where required)
- Thermo-elastic analyses (including temperature mapping)
- Shock Analyses (modal, transient and according to ECSS-E-HB-32-25A)
- Vibro-acoustic (BEM & FEM)
- Model correlation with test data
- Model condensation (Guyan and Craig-Bampton)
- Fatigue verifications according to ESAFATIG, EN 1993-1-9
- Fracture mechanics analyses with ESACRACK, NASGRO
- Optimisation
03
Component verification
Dedicated verification of components like:
- Bolt verifications according to ECSS-E-HB-32-23A, VDI 2230, DIN 18800, EN 1993-1-8
- Insert design according to ECSS-E-HB-32-22A
- Electronic components on PCBs (Steinberg's rules)
