| Summary: | In the paper a possible scenario for the occurrence of the local buckling of the wall of the thin walled aluminium mast is analyzed. It is assumed that the hook of the auxiliary crane of the rubber-tired marine crane buckled to the lateral mast-supporting wire rope during the retrieval motion from the pier. The consequences of an unintended crane action on the mast of the sailing boat are studied using combination of analytical calculations and FEM. The complexity of the mast - mast wires system, the big displacements and nonlinear material characteristics are taken into account. The properties of the tempered aluminium alloy are included as well as properties in the heat affected zone in the vicinity of the welds. On the basis of the calculated internal forces and moments in the mast and wire-ropes, the possibility of occurrence of different types of failure are studied. The estimated possible damages are compared with actual damages. |
