Abstract
A wire rope is comprised of several metal wires which are wound together like a helix and it can resist relatively large axial loads, as compared with bending and torsional loads. A shipbuilding crane for erection such as a floating crane, a gantry crane, and a crawler crane hoists up and down heavy blocks by using these wire ropes. Thus, it is necessary to find dynamic properties of a wire rope in order to safely lift the blocks using the crane. In this study, a formula for calculating the tension and torsional moment acting on wire ropes of the crane was derived based on the existing study, and then dynamic simulation of the crane was performed based on the formula. The result shows that the dynamic simulation can be applied to find the safe method for block erection of shipyards.
