Abstract

The demand for light cranes in the fields of intelligent manufacturing and warehousing logistics is increasing day by day. The core component, the drum, is developing towards precise parameters and lightweight structure. Traditional design relies on empirical formulas, and the matching of structural parameters is unreasonable, which is prone to strength redundancy or stress concentration and makes it difficult to balance lightweight and reliability. This study takes the drum of a light crane as the object. Based on the principle of wire rope winding and strength standards, the theoretical calculation of key parameters is completed. Through SolidWorks modeling simplification and ANSYS Workbench static simulation, the start-up impact condition is simulated and its stress, strain and deformation characteristics are analyzed. The results show that the stress and deformation of the designed drum are both within the mechanical limits of Q235B material, with no plastic damage, achieving a balance between strength and lightweight. This research clarified the matching rules of drum parameters, verified the scientific nature of the design, and provided a reference for the precise design of similar drums and the digital development of core components of light cranes.
