Design and analysis of marine hoisting and moving vessel crane based on FEA |
| |
| Abstract: | Some marine hoisting and moving specialized vessel crane was designed. Its max lifting capacity, max lifting height was 460t and 100m, respectively. Flexible finite element model was proposed including sheer-leg, jib, and turntable structure. In the model, structural element, solid element, connector and constrain equation were used properly. And mechanical properties of the crane were analyzed under critical working conditions. Designing flaw was found and modified. Finally, strength, stiffness and buckling of the crane were studied. |
