A structural design and optimization of a fixed boom system using a computer-aided engineering-integrated topology optimization approach

Topology optimization provides an effective approach for achieving efficient conceptual designs in mechanical structures. Traditional design practices based on experience and trial- and-error methods are time-consuming and lack systematic optimization. In this study, a computer-aided engineering (CAE) framework is employed to perform static and topology optimization analyses of a fixed boom system. The finite-element-based optimization aims to minimize weight while preserving the required structural stiffness under identical loading and boundary conditions. The results reveal critical stress concentrations on the boom pins and arms, guiding the material removal process during optimization. The proposed approach demonstrates that integrating finite element analysis with topology optimization enables the development of lightweight, high-stiffness boom structures suitable for industrial lifting applications.
