This thesis presents the topology optimization process of a mounting bracket using solidThinking Inspire and SolidWorks. Topology optimization can be used whenever you need to improve an existing design or design a brand-new part which needs to fit in a specific space, be lightweight and a withstand certain forces. It works by taking a block of material and shaping it by removing material, minimizing or maximizing part mass, displacement or compliance to fulfill set limits such as maximum stiffness or amount of deformation allowed. The reduced weight tied to cost benefits provided by topology optimization can be seen in various industries.
The goal was to reduce 70 % of the original weight. After optimization the achieved reduction in weight was 66 % using Inspire and 67 % using SolidWorks. The maximum stress was increased from 145 MPa to 422 MPa using Inspire. Factor of safety was between 1 and 6. Due to frequent errors in SolidWorks no post FEA- analysis could be performed for comparison.
Each part was 3D Printed using Arcadas MakerBot Replicator 5 for visual demonstration.
