A topology optimization design of a crane hook

Abstract

The goal of this research was to demonstrate the effectiveness of optimization techniques and test the possibility of using ABS plastic to optimize the existing crane hooks that use these techniques. Based on the optimization results, verification of the modified hook, and structural stability, this optimization reduces the weight of the crane hook while maintaining durability. This study utilized 3D modeling software to optimize the design of an existing hook, ensuring both sufficient strength and weight reduction. The research analyzes the results, concentrating on the stress that falls within the material strength limit. The research begins by utilizing a maximum of 1 kg of ABS plastic and a 5 kg liftable load. Using topology techniques, the study proposed five models that meet technical requirements. As a result, the proposed structure is highly economical and optimized in terms of materials and time, while still ensuring working performance. This work utilizes 3D modeling software for optimization design. It was effective to combine 3D printing manufacturing technology with size considerations. This article serves as a reference for future research and hook design.
