From Topology Optimized Concept to Detailed Design via Implicit-based Geometries and Non-linear Finite Element Analysis

Sammanfattning: A workflow to go from topology optimized concept to a detailed design was created in this thesis. This was done through the use of Implicit-based geometries and Non-linear finite element analysis. The workflow was created by creating a script combining three different programs to create STL files, refine them and to measure reaction force of the design. This was done cause there is no established way to get a detailed design in the earlier stages of designing a product. Using this approach with Implicit-based geometries a design which can be examined morphed and tested in the earlier stages of the design development can be generated. In this thesis the workflow was implemented on two different designs were both was morphed in three different regions with a magnitude varying from 0-1 and then measured reaction forces with non-linear finite element analysis for each combination of the magnitude. The reaction forces and volume output were then used to create a metamodel which was optimized to minimize weight whilst keeping a certain reaction force. One of the designs was given from Epiroc to improve from their previous design, and the thesis concluded a design with a weight reduction of 7% with reaction forces being higher in three out of four measuring points.
