Abstract

The analysis of stiffness and strength of a complex topology optimized part designed for 3D printing is a new method to design product beyond a certain level of complexity. The complex part chosen was an engine load bracket which have four load cases applied to it. Topology optimization is a method that used to solve design problems which conventional manufacturing process have constraint during design stage to ensure feasible design. The purpose of this study is to develop an optimized engine load bracket by complying all the requirements assigned. In order to produce a optimized product, many areas need to be studied and analysed such as the material properties, strength, weight, 3d printing fabrication and design improvement. This project carried out all of the necessary background research required to sustain the design requirements. Finite element analysis was used to simulate the conditions of various load applied. This project selects two types of topology optimization method I with design control II without design control to optimized engine load bracket. The result shows two different geometrries after topology optimization was applied. The design result shows different geometry, strength, and weight reduced after topology optimized. The results were compared to original model to analyse the strength after topology optimized was applied. The fabrication of the optimized parts is analysed to have the minimum material usage when printing. 3D printing used support for parts with overhanging geometry, the design improvement after topology optimized is to avoid overhanging geometry of the product. The findings suggest that improvement of the bracket will leads to lower material usage of material and time consumption to fabricate the parts with 3D printing technologies. The parameter findings also related to final design of engine load bracket and fabrication with 3D printing. The final design of engine load bracket with using topology optimization method has potential for future developments and manufacturing. During the development and fabrication of the engine load bracket, some areas for improvement were recognized and future recommendations were suggested.
