Structural optimization

Automotive lightweight seat

Automotive lightweight seat (Engineering by M.TEC)

The component geometry is based upon structural optimisation – the CAD model is developed using these calculation results, followed by wall thickness optimisation and fibre layer optimisation.

Vessel lid structural optimisation

Vessel lid structural optimisation ENGINEERING by M.TEC

Optimisation of the component geometry of a vessel lid with the aid of structural optimisation, resulting in higher stiffness and lower stress with the same component weight and material usage (in the picture below: initial geometry, above: optimised geometry).

With structural optimization, load-compatible component structures can be calculated. Based on any number of load cases and a given installation space, components in which only a minimum amount of material has to be usedcan thus be developed simulatively. Therefore the integration of structural optimization is an essential part of the development of lightweight components.

In addition to the pure optimization of the shape of the components, the topology optimization, also wall thicknesses, beading or fiber orientations can be optimized. 

Benefits of structural optimization

  • Finding a component structure suitable for the load
  • Optimization of the deformation behavior
  • Reduction of component deformation
  • Reduction of weight and material usage
  • Elimination of natural frequencies
  • Optimization of beaded structures

Structural optimization and lightweight engineering

Our engineers are specialized in deriving the corresponding comparative loads for a targeted structural optimization from the multitude of requirements placed on a component.

The goals of structural optimization differ greatly

In addition to the development of load-compatible component structures and the increase of component stiffness, the elimination of natural frequencies or the optimization of the fiber layers in FRP components are also part of the objectives of structural optimization. Based on the many projects in which we have used structural optimization, we have the necessary know-how to derive a geometry from the calculation results that remains mechanically optimal but can still be implemented with minimal costs.    

Simulation software for structural optimization

For FE-calculations, we use the following programs:

  • Marc/Mentat
  • Abaqus
  • HyperMesh
  • Radioss
  • OptiStruct
  • MotionSolve
  • Digimat
  • Matlab/Simulink
