Design Optimization of Single Overhead Crain Girder using Finite Element Analysis

Abstract

This study aims to develop strategies in the field of structural optimization and implement these strategies into the design processes. The single-sided swing arm has been selected as the subject of this study. The primary objective of this project is to reduce the mass of an existing steel girder arm, a component of a 1-ton capacity overhead crane, through the application of topology optimization techniques. This weight reduction is essential to enhance cost-effectiveness and operational performance. To achieve this goal, the Finite Element software Ansys, equipped with multiple modules, has been utilized. Ansys is responsible for preparing the finite element model and conducting modal and static analyses. Topology optimization is performed using Inspire. Static analysis is carried out, considering the effective dynamic load on the crane girder in accordance with IS codes. The optimization method applied in this study has successfully resulted in an 18.97% reduction in the mass of the existing girder.
