Topology optimization is an optimization method to reduce material usage while also enhance the tension resistance of a part. This process creates complex, organic shapes and therefore,3D printing is known to be able to print also complex structures without increasing manufacturing costs. The aim of this work was to carry out a topology optimization with suitable parts and to determine the mass reduction as well as the change in tensile stress.
The thesis was divided in two sections. The first part dealt with the theory behind the topology optimization and their components. For this purpose, literature research was carried out first.The second part dealt with the practical application of the topology optimization using the Solid works simulation software. Therefore, 3D models have been created and first analyze dusing the FEA to get an insight about the occurring tensile stress. Then the optimization was carried out and checked by a second FEA. Finally, the results of these analyses were discussed.
The results of these analyses showed, that the topology optimization is a strong software tool for material use optimization. However, Solid works only removes material and is not able to enhance the tension resistance of a highly loaded area. Furthermore, the results have shown that not all material that is classified as removable by the software may be removed.
