摘要

Topology optimization is a simulation driven design technique used for creating an efficient material layout for a given design region, constraints and loading conditions. The goal is to maximize the system's performance while minimizing the weight and meeting other functional requirements. The aim of this work is to optimize an existing aircraft bracket using Topology optimization technique. Topology optimization is performed in Altair Inspire software without using any shape control on the basis of five-volume retentions. Volume is specified as 20%, 30% 40%, 50% and 60% of the total design space volume. Post optimization analysis of all the five optimized geometries is carried out. Finally, one model based on optimum results is selected and the smoothing process is carried out using Polynurbs fit tool. The Final optimized model has a weight reduction of 46% and a significant stress reduction of 28%, 54.4%, 49.8% and 47.7% in vertical, horizontal, oblique and torsional load cases respectively..
