Computer-aided rotary crane stability assessment

This paper introduces a computer -aided approach for evaluating the stability of rotary cranes. Utilizing the Motion add -in within the SolidWorks package, a comprehensive numerical stability analysis was carried out. The interaction dynamics between the crane's support system and the ground were modeled employing linear springs, while the rope system was characterized by a blend of linear spring and damper elements. The term "temporary loss of stability"was introduced to describe scenarios wherein one support loses contact with the ground. Furthermore, ramifications of overlapping control signals on crane operational safety were investigated. Validation of the numerical findings was accomplished through experimental tests conducted on an actual crane. This integrated methodology not only enhances the understanding of crane stability but also offers practical insights for optimizing crane operations in real -world settings.
