Alcoa Optimized Bearing Bracket · 模型 65075
This study was developed at CREAMI ( Center of Reverse Engineering and Additive Manufacturing Innovation) Lab. of University of Naples “Federico II” for a thesis in mechanical engineering. The objective is to redesign the bearing bracket made by Alcoa Fastening Systems & Rings using DFAM tecnique. This tecnique allows the topology and shape optimization, and the weight minimization. One of the most important aspects of AM, is the possibility to create highly complex geometries. That’s exactly why initially AM was limited to the production of prototypes, but continuing improvements of speed, surface quality, material properties and price have given way for the production of end-products in a growing number of markets. The bracket is designed to be produced by additive manufacturing, and the project shall also minimize the necessity of support structures. The analysis and optimization steps were developed through the use of finite element solver programs (Inspire, Optistruct Altair Inc. ). The mechanical feature, like elasticity modulus E, Poisson ratio ν, are defined in the challenge. After the optimization of the original component, Inspire gave us a new bracket’s model which works in safety condition, despite having a reduced weight. Being based on that shape, the bracket has been redesigned in Solidworks (image 1). The final result is visible in images 2 to 3. We can assert, on the basis of the analysis made using Inspire (images 4 to 6), that the component, subject to the loading condition reported in the challenge, works with safety coefficients which guarantee the integrity for every parts. The mass has been drastically reduced compared to the original component (0.9134 pounds compared to 1.9551 pounds). The favorite printing direction for the bracket is shown in images 7, 8 and 9.
