ELiSE Engineering offers you a wide spectrum of engineering solutions. A strong interconnection of the construction, calculation and optimization provides excellent conditions to develop efficient and client-specific lightweight solutions.
For the CAD construction we attach great importance to a model structure with variable parameters. This approach suitable for simulation and optimization respectively later allows a bidirectional data exchange with FE and optimization programes. Depending on the requirements, the verification is carried out with static and/or dynamic analyses as well as crash and multiple-body simulations. Therefore the final design represents the requirements of the specifications and the client-specific expectations concerning an optimized lightweight design. When adapting to manufacturing restrictions, we also factor in additive production processes (ELiSE AM) next to established procedures.
- CAD with CATIA, SolidWorks, Rhino
- FEM calculations with ANSYS, HyperWorks, LS-DYNA, NASTRAN, Marc/Mentat
- Simulation of NVH, acoustics, CFD, crash- and multiple-body simulation
Already at the beginning of the development process we use topology optimization as a method to determine optimal load paths. The most comprehensive step during optimization is the parametric optimization. Coupled to CAD, discrete parameters such as the amount of ribs, as well as continuous parameters such as wall thickness or the orientation of surfaces can be modified iteratively. Through evolutionary algorithms, the natural improvement process is represented in technical form. Therefore the optimal parameter values for a given load spectrum can be identified. Furthermore, the concepts defined in the ELiSE concept are dimensioned to reach the optimum. Based on distinct research results, adaptive honey-comb structures are utilized to create finely branched and load specific stiffening structures. These structures are aligned according to an algorithm based on natural models. The use of topography, thickness and beads optimization give your product the finishing touch.
- Bionic topology, thickness and bead optimization
- Parametric optimization with design of experiments and evolutionary algorithms
- Mechanical structural design and optimization taking into consideration complex geometries
- Load-optimized lattice structures especially for AM
We are convinced that the two areas design and calculations, which are often treated separately, strongly influence one another in a bidirectional way. This effect is especially severe as soon as a strongly optimized lightweight structure is required. For a coupling between CAD, FE and optimization systems, mainly own developments are deployed next to commercial interfaces. In this way our expertise is applied in the area of programming e.g. the application for the automation of development processes and the coupling of CAD and FEM with the optimization system.
- Coupling of CAD and FEM for optimization (simulation-driven design)
- Automation of CAD and FEM development processes e.g. for automated structural design
