Structural analysis

From simple statics to complex dynamic simulations, we have answers to your structural problems. With the help of computer-aided simulation we can evaluate your product in a fully virtual environment.

Since 2002, AeroFEM has performed static and dynamic structural analyses of over a thousand projects for more than 80 international customers. With the aid of numerical calculations (FEA), we can investigate the linear as well as the nonlinear behavior of mechanical parts and assemblies. Loads are calculated according to engineering standards or determined by using dynamic multi-body simulations. In aerodynamic situations, loads can also be determined directly with CFD calculations (see flow simulation) and applied to our structural models. Where applicable, the verifications are also supported by analytical methods. Upon completion of the analysis, relevant documentation is prepared for approval, and, if required, coordination with regulatory authorities is arranged.
