TOPOLOGY OPTIMIZATION FOR MOUNTING BRACKET

Abstract

The need for lightweight and structurally efficient components is urgent in today's aircraft operating environment where performance, safety and fuel efficiency play a huge role. This thesis discusses the use of topology optimization in the design of mounting brackets, which constitute important components for transferring loads between structural elements as well as aircraft appendices. One effective computational technique for establishing the ideal material distribution in the design space is topology optimization. Finding the ideal material distribution to satisfy functional needs while reducing weight, preserving stability, etc., is its primary objective. Two topology optimization techniques—density-based and the level-set based—have been illustrated in this thesis. The thesis starts with aircraft-specific design specifications and limitations, like material qualities, loading conditions, and geometry limitations. Two distinct mounting brackets were built in Ansys SpaceClaim, after which they were changed utilizing topology optimization methods to reduce weight while retaining stiffness. The original bracket and the optimized bracket are then contrasted to identify variations in structural characteristics, material efficiency, etc. The results of this study demonstrate the potential of topology optimization in the aerospace industry, which enables manufacturers to create mounting brackets with reduced weight, low costs, and reduced material consumption. In addition, the ability to create lightweight high-performance designs is a compelling argument in favor of aviation applications, as it allows for lower fuel consumption and emissions, and the use of more sustainable processes.
