In our quest to design ever faster and more accurate systems we require evermore lightweight and stiff parts. In order to efficiently design these parts and get the most performance out of a limited amount of material I’ve developed a custom set of software tools which allows me to optimise a structure based on requirements such as it’s stiffness, strength or flexibility. Below you can find an example of a sensor bracket optimised to withstand a set of opposing loadcases.
Based on a problem definition and design space (1) the software uses the SIMP method to solve the topology problem. The result is a set of voxels (2) where every voxels contains information about the local material destiny. This information is transformed back into a mesh and interpreted using CAD software. The resulting design (3) is then validated by performing a stress analysis (4).
